  I don't think this is possible (or at least not easy).
What you're really asking for is an Excel filter; seems
to me the easiest (?) way to do this would be in Visual
Basic, or to do search and replace in your work sheet,
replacing <sup>2</sup> with (superscript)2, and so on
[it doesn't look like Excel's search-and-replace has
a regular expression facility, but if you only have
a few worksheets and a limited number of sub- and
superscripts (say sub/super 1,2,3,+,-) this shouldn't
be too painful ...
