One midi instrument - multiple tracks - with solo and mute

I'm looking for a way that one midi instrument can have multiple midi channels feeding it, but also with solo and mute capabilities. The usual answer to this question is to: select your software instrument track, then go to the Track menu and select "Other>New track with same instrument" This does work, but these additional tracks cannot solo or mute their midi regions. If you use solo or mute, it solos or mutes the instrument, and all the tracks solo or mute the instrument at once... but what I want is to solo or mute the tracks individually.

And I should add - the Power buttons on each track can be used to mute the individual tracks, so that's a half-way work around, but using that to solo is time consuming.

Any ideas?
