Softkey Function "Assign On/Off" follow Select

Would it be possible to setup a softkey to toggle the selected channel’s assignment to groups.

Currently I have 2 soft keys setup that toggle a mics routing into a group or directly to mains. I use this to assign all of my BGV mics to a processing group that has doublers and compressors that work well with a group but when someone gets the “spirit” in them, I would like to setup a quick way to reroute the mic direct to the LR bus.

Currently this exists, but can only achieved by using a soft key that is setup to toggle the LR & group state On/Off, but the action can only be assigned to one mic specifically. I am hoping there is a way to change the “Source Channel” to “Follow select,” so that as they start speaking on a BGV mic I could select that mic, hit the toggle and re-route them.
