As I said, you can do it via Find/Replace.
You could even
record a macro for that!
Nevertheless, insert:
Code:
With .Range.Find
.ClearFormatting
.Replacement.ClearFormatting
.MatchWildcards = True
.Forward = True
.Format = False
.Wrap = wdFindContinue
.Text = "(PV: )RR([0-9])"
.Replacement.Text = "\1\2"
.Execute wdReplaceAll
.Text = "(PV:)RR([0-9])"
.Replacement.Text = "\1 \2"
.Execute wdReplaceAll
End With
before the final 'End With' in the code you're already using.
