formatting text

[Augustus]

I have a very simple problem.
In Word or Excel, we could have text both in Normal,
follow by superscript and/or subscript.

Could I do this in Visio? I'm currently using Process
under Game-Sarson, I can't have text both in normal and
subscript mode (I tried Format Text/Position/subscript,
but it simply return the selected text back to normal; i
can have either one, but can't have both). Is this
possible?

Thanks
