I don't know about modifying a system command but if it were my command, I would look into combining a PMTOVRPGM program (to look up and present the choices) and a VLDCKR program (to enforce the choice(es)). I have used both (although not together on the same parameter) on my commands.

Suppose you were tasked with writing a "super prompter" program for a
system command: one that expands on the existing prompt, e.g., where the
existing command asks for the names of one or more fields in a file, the
"super prompter" would allow the user to choose those fields from a list.
How would you approach such an undertaking?
