I’ve found a reasonably good workaround involving some macros programmed in AutoHotkey, triggered via my Avid S3 which more or less allows me to do VCA spill and to show/hide tracks simultaneously on the arrange page/control surface with Visibility Agents. It’s not quite as good as the real thing but it’s pretty close.
Happy to share the details but be warned it’s kind of complicated to set up. Once set up though, it works very well.
