You can't handle events from a collection. The easiest solution is to use a separate class to handle the button events, make a collection of those classes in your multiple buttons handler, and pass the button from the class handling the single button to the class handling multiple ones on an event.

Class CSingleButton

Public buttonsHandler As CButtons
Public WithEvents btn As Access.CommandButton

Private Sub btn_Click()
    buttonsHandler.HandleClick btn
End Sub

Class CButtons

Private ButtonHandlers As Collection

Const MODE_DEBUG As Boolean = True

Public Sub LoadButtons(ByRef TheForm As Access.Form)

    Dim ctl As Control
    Dim btnHandler As CSingleButton
    Set ButtonHandlers = New Collection
    For Each ctl In TheForm.Controls
        If ctl.ControlType = acCommandButton Then
            Set btnHandler = New CSingleButton
            Set btnHandler.btn = ctl
            Set btnHandler.buttonsHandler = Me
            ctl.OnClick = "[Event Procedure]"
            ButtonHandlers.Add btnHandler
        End If
    Next ctl

End Sub

Public Sub HandleClick(btn As Access.CommandButton)
    If MODE_DEBUG Then debug.print btn.Name & "_Click"
End Sub
