Does anybody know if you can put a prefix on note numbering/order list (see below.)

My drawings have General Notes, Removal Notes, Installation Notes, & sometimes Testing Notes. For General Notes, these are number 1 thru whatever. For removal Notes we put an "R" in front of the number to differentiate it from General Notes. "I" for Installation & "T" for Testing Notes.

You can define your 'numbers' in MS Word but I can't seem to find a way to do this on a SolidWorks drawing. Is this possible? If not, can it go on a wish list for the next release.
