Side chain quick selection

I would love a feature that allows to quickly select tracks to add to sidechain.

For instance, I edit a plugin and open the sidechain dialog window. How about a shortcut like Ctrl, and if I keep the sidechain window open AND click on any track on my project view or mix console, it adds it to the sidechain directly (way faster than having to select from a drop down menu!)

It would be simple but a good workflow improvement

Thanks!
