The Lighting Controller

I want to set some certain lights so they simply come on and stay on until I hit that button again (to turn them off). The catch is... I want to be triggering other scenes in between. Is that Possible? I'm thinking if the "freeze" feature was available as an attribute for individual buttons. I'm using the Xpress 512.

Thanks!

I think I figured it out... I can trigger simultaneous scenes as long as they're coming from different "Pages". That works for me.
