OK, this is completely inelegant and I'm sure someone else can Ido-Millet a better solution in two clicks. But here's one idea. You can add a command object that filters the employee list to actives and then let your parameter use that pre-filtered list. My example is with an item. I just want the user to pick items in the DC product line. It's my first time using a command (must keep straight face)...ok, using a Crystal Command. So for all I know it may take it six hours to run. But it worked for me. The third image shows where Add Command lives, for any other noobs like me.
