Highlighting Zones

Am I correct that there's no way to highlight a particular zone in the seating map with any kind of in-client styling using TR_SEAT_STATUS?

Obviously holds show up a particular way, and "not in allocation" can be utilized for its own purposes, but is there any way to highlight Available seats in a specific zone with that table? Open to other ideas as well. 

This is specifically for use in the client, not online.
