Command Choice Program

The parameters to a command choice program include the name of the command and the keyword of the parameter for which choice text or possible values are to be retrieved. In theory this allows a single program to be used as the choice program for several commands/parameters.

My problem is that I need to use a choice program for different elements of some complex list parameters, e.g.:

PARM KWD(PARAM) TYPE(L_PARAM)

L_PARM: ELEM TYPE(*CHAR) LEN(1) CHOICE(*PGM) +
CHOICEPGM(CHOICEPGMA)

ELEM TYPE(*CHAR) LEN(1) CHOICE(*PGM) +
CHOICEPGM(CHOICEPGMB)

Question:

So far as I can make out, I'm stuck with having two choice control programs here (CHOICEPGMA and CHOICEPGMB) as, so far as I can tell, there is no way of telling from the program parameters which list element the call relates to. Anyone know better?

It would be very nice if IBM could add an extra parameter, e.g. a number indicating which element of the parameter the call relates to, where the parameter is a list parameter. This would reduce the number of objects required by our system by about a dozen. We already have a generic choice control program, which is called by the various actual choice control programs used by our commands in the circumstances above, but the problem is we are still left with multiple choice programs because of the issue described above (albeit very trivial ones).
