Is it possible to use macros inside the argument of an \index command?

My problem:
I have a macro (\XP) which, depending on a flag, expands to one of two
possible texts, e.g., the call:

   \XP{IMAGE}

will produce either the text "FGL/IMAGE" or the text "agX/IMAGE". What
I would like is:

   \index{\XP{IMAGE}}

which should create an index entry under "F" or "A" depending on the
flag. As you might have guessed, it puts it under "X"!  Telling IdxTex
to ignore the \XP macro works fine, but then it puts it under "I"!!!
I've tried using \expandafter, but came up with nothing new.

So, is there any way of making the \index command above work?
