There’s been quite a few posts about this, all pointing out the same shortcomings.
Unfortunately Steinberg did not feel the need to comment on any of these, so I am guessing nothing is going to change in the foreseeable future.
I gave up on this feature almost entirely, I only use the vis switches for separating track types in the three mixers, one mixer holds all midi, audio and VCAs, second mixer only shows busses and the third FX channels. Anything else created a mess.
