HOW TO DO I COMP MULTIPLE TRACKS AT ONCE - Like drums?

I think I've read this somewhere so if it clearly outlined somewhere a link to it is fine.  Otherwise, how can I comp a group of tracks at the same time like say multiple drum takes or guitar takes with multiple mics?   THANKS!

I do this a lot. But having the foreknowledge that I am going to do this, I make a few preparations ahead of time to make it easier.
 
1. Go to Preferences>Record (Under Project).
2. Towards the bottom, select "Only Group Clips in Folders" under Multi-track Grouping.
3. Select Apply and close the Preferences window
4. Put all of my armed tracks in a folder
 
Now, as I record (in Comping mode, with mute previous takes selected as well in Preferences>Record) everything is automatically grouped.
 
Later, when I open Take Lanes to comp the best parts, I select the "Clip Headers" to ensure that when I select a clip, the all clips in that group are also selected. So even though I may only have the "Snare" drum visible, I am assured that all other drums in that group are selected. When I comp like this, all 14 of my drum tracks are comped right along.

THANKS!   The bad news is I did not know to set that option but the good news is that my question is more for future recordings so now that I know....   I may try to do it manually just to see how well that could work in case  I need to go back.   I does seem that the option to group clips in folders should be default as other than basic organization and mass soloing, there are not a lot of other obvious benefits to grouping but this is a huge benefit .

It does seem that the option to group clips in folders should be default...

It's a per-project setting so it'll save with project templates.
