[with whatever follows] would need to feed back out to the (command) function an AutoCAD command name or input to such a command if you're already in it.  That would mean you can't get around whatever the (AMPARTREF) function needs you to do.  You would probably need to make an altered definition of the function without the asking for unneeded properties, or find another way to accomplish the task [I can't suggest anything without an idea what (AMPARTREF) does].
