Audition fx racks deactivate accept channels that are solo'd

Ok... I mix audio for bands and like using Audition. I use a fair amount of plugins that at a certain point boggs down the playback... I can turn them all off if I am working say on the drums... but I have to do it manually which is a pain.. A nice feature would be to have audition just shut all of them off automatically. What ever is solo'd just stays on unless you turn it off manually... it would make things run faster with out manually doing it for every track. Thanks!
