You could use a macro like:
Code:
Sub Demo()
Application.ScreenUpdating = False
Dim Shp As Shape, iShp As InlineShapes
With Selection
For Each Shp In .ShapeRange
With Shp
.LockAspectRatio = True
.Height = InchesToPoints(0.7)
End With
Next
For Each iShp In .InlineShapes
With iShp
.LockAspectRatio = True
.Height = InchesToPoints(0.7)
End With
Next
End With
Application.ScreenUpdating = True
End Sub
Simply select the range to process before running it.
