If you really want to get busy with Mid-Side processing, your best bet is to build a Rack. All you need is an Audio Effect Rack with two chains:

Drop a Utility device into both chains. Set the Width of the one in the Mid chain to 0%

….and the Sides chain to 200%.

Now, you’ve got a rack that has no impact on the signal whatsoever – except for the fact the middle and sides have been spit into separate chains so they can be processed seperately. Even if you’re just using EQ, there’s a big advantage to doing it this way because you can easily listen to the middle and the sides individually.
