initial answer

You can format the partial string using characters.

Code below appends your sample string to test string (300 characters long), then makes the last three italic, the three before that bold.

Sub LikeThis()
Dim StrIn As String

StrIn = "aaaabbbccc"

[a1] = Application.Rept("xyz", 100)

[a1].Value2 = [a1].Value2 & StrIn

[a1].Characters(Len([a1]) - 5, 3).Font.Bold = True
[a1].Characters(Len([a1]) - 2, 3).Font.Italic = True

End Sub
