Aqui está uma macro VBA para copiar todos os botões de um slide para outro:
Option Explicit
Public Sub copyButtons(sourceSlide As Slide, targetSlide As Slide)
Dim shp As Shape
If sourceSlide.Name <> targetSlide.Name Then
For Each shp In sourceSlide.Shapes
If InStr(shp.Name, "Button") > 0 Then
shp.Copy
targetSlide.Shapes.Paste
End If
Next shp
End If
End Sub
Public Sub testCopyButtons()
Dim sourceSlide As Slide
Dim targetSlide As Slide
Set sourceSlide = ActivePresentation.Slides(2)
Set targetSlide = ActivePresentation.Slides(3)
Call copyButtons(sourceSlide, targetSlide)
End Sub
Os botões copiados herdarão os links e ações dos botões originais.
