    OK yes I am providing an answer to my own question....will work on getting the program for the suggested method.

    Here is the code that is working (important bits only):

    Dim all kinds of stuff
    
    ' Get the year and month of interest [User inputs the year and month they want the data analyzed YYYYMM
    
    YY_MM = InputBox("Enter year and month of the daily cycles you want to analyze eg YYYYMM, no day, A_, B_ or _TC needed", target = D4, AI4)
    
    'separate the YYYYMM date to YYYY and MM
    F_year = Left(YY_MM, Len(YY_MM) - 2)
    F_month = Right(YY_MM, Len(YY_MM) - 4)
    
    'Determine # of days in the month 'The code below is from http://msdn.microsoft.com/en-us/library/aa227538(v=vs.60).aspx and it saved me from an If than nest from hell
    
    mMax = DateSerial(CInt(F_year), (CInt(F_month) + 1), 1) - DateSerial(CInt(F_year), CInt(F_month), 1)
    
    'The user must say where their data is by listing the path on the worksheet.  in this case it is a set template
    
    sDataPath = Worksheets("Data").Cells(1, 4).Value ' value located in 1st sheet of workbook
    
    
        For i = 1 To mMax 'OK this is the file insertion For the A
    set of data files
    
            If i < 10 Then   '  Need to add a zero to get the correct file name
                Z_singdig = "0" + CStr(i)
            Else
                Z_singdig = CStr(i)
            End If
    
            sDate = "A_" + YY_MM + Z_singdig + ".csv"   ' looping through list of dates ..
    
             'Label the data column with several file names so one can read it
            Label_F_Name = sDate + "........................."
            F_name = sDataPath + sDate
    
            With ActiveSheet.QueryTables.Add(Connection:="TEXT;" + F_name, Destination:=Range("D1048576").End(xlUp).Offset(1, 0)) 'insert the next file at the bottom of the first
                .Name = Label_F_Name
                .FieldNames = True
                .RowNumbers = False
                .FillAdjacentFormulas = False
                .PreserveFormatting = True
                .RefreshOnFileOpen = False
                .RefreshStyle = xlInsertEntireRows
                .SavePassword = False
                .SaveData = True
                .AdjustColumnWidth = False
                .RefreshPeriod = 0
                .TextFilePromptOnRefresh = False
                .TextFilePlatform = 437
                .TextFileStartRow = 1
                .TextFileParseType = xlDelimited
                .TextFileCommaDelimiter = True
                .TextFileColumnDataTypes = Array(1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1)
                .TextFileTrailingMinusNumbers = True
                .Refresh BackgroundQuery:=False
            End With
    
    'report out the number of rows in each data file so I can use those as cell ref's later
            numofrows = Application.CountA(Range("D:D"))
            rownumout = numofrows - Corrtrow ' num of rows just added by the last file
            rowprtinc = 30 + i
            Numrowprt = "'data'!" + "DE" + CStr(rowprtinc)
            Range(Numrowprt) = rownumout ' entring the number of rows into a table on sheet 2
            Corrtrow = numofrows ' must track the current row num so the next row num can be corrected ...yeah that worked
    
        Next i
    
    ' do the same for the B set of data files..not shown here
    
    End Sub
