Loop through sheet set

[demetrius.adams]

I have around 200 drawings in subset of a sheet set. Half of the sheet numbers are just numbers and the other half are numbers with a D at the end. I want to add a dash before the D if the sheet number has one. Basically, I need to make this

1
1D
2
2D
3
3D

look like this

1
1-D
2
2-D
3
3-D

I think only VBA has access to edit the sheetset so a lisp can't be used. I can write the loop to work in excel VBA, but I'm having trouble in autoCAD VBA because I don't know how to call out all of the sheets in the subset or the property that needs to be changed (the sheet number).

I'm not sure if this will help at all but this is what I wrote that works in excel VBA. The lines in red are what need to be changed.

Public Sub Demolition()


 For Each cell In Range("E6:E13") 'Need to define every sheet in a subset
 
 If Right(cell.Text, 1) = "D" Then 'Need to call out the sheet number property
 
 cell.Value = Left(cell.Text, Len(cell.Text) - 1) & "-D" 'Same as above
 
 End If
 
 Next cell
 
 
End Sub
