Track Link/Group

Please consider adding the ability to link two or more tracks together with a parameter selected (Gain, FX Wet/Dry, etc). That would allow the user to preserve the relative mix among the linked elements with a group fader.

In my example, I created a binaural beat with two sine waves 4Hz apart; I panned one left and one right. A group fader or slider would allow me to freely adjust the gain.
