Create a workspace for every channel that you desire. That’s not even limited to FX channels. I usually create workspaces for channels with several inserts.
I should have mentioned, my suggestion is far from ideal especially since if you use key commands there are only 9 or 10 KC’s available before you run out and have to use a mouse in the Workspace box. While workspace does work, it really wasn’t specifically designed for what you are looking for.
