Auto Stack after edit in Photoshop

[TobyTucker]

I was just curious if anyone knew of a way to auto stack the original with the photoshop edited file. When I am editing, I hit ctrl-e to take my photo into photoshop. Once I finish and save it back to lightroom, it has two side by side files. One is the original and the second is the edited version. Is there a way to have lightroom automatically stack this under the edited version. I know I can go into library grid mode and hit photo>stacking>collapse all stacks but wanted to do this automagically.

Thanks,
Toby
