Sampler Track Suggestion: Let us mute Left and Right channels, as well as an MS decoded middle, and Phase inverted

Something extremely fundamental in sampling… is isolating sounds by channel.

To be able to quickly mute Left/Right channels, or even is it was ms decoded to obtain the middle information only.

I would then like to see a mono sum at the output of the sampler track so that even if the sampler track, which it would in this case, be stereo… if I have only the right channel active, I can sum it to the center in the Cubase mixer/channel fader/panner input.
