I have a document where the author has used superscript to refer to footnotes. This doesn't work in our system, the footnotes need to be regular text enclosed in parentheses. The footnotes are sometimes a single number, sometimes multiple numbers separated by commas, and sometimes a range separated by a dash.

So Citation Here superscript 19-21 needs to be changed to Citation Here (19-21)

I can't see a way to do it using Find and Replace. I can obviously get rid of the superscripts leaving plain text, but can't add the parentheses since it doesn't seem there's a way to say "replace this formatting but add this leaving the original text intact". Is there a macro that would work?

Thanks so much in advance for any advice.
