How are people handling Owner Furnished, Owner Installed / Owner Furnished, Contractor Installed / NIC?

I believe most companies have the graphic standard that those objects are to be grey or halftone, hidden line, or something similar...but I'm running into brick walls

What Ive Tried:
1. Adding a parameter to all modeling objects under phasing. Then tried to apply a filter, but it wont let me pick the newly created multi-category parameter.
2. Made a Workset for these items. Works great until you have to group a unit and copy it around a bazillion times. the group defaults to the active workset...

Our company does tons of multi-unit housing and use groups a lot. So option two sounds the most logical but is a no go..........


any thoughts or words of inspiration????
