They're planning to add a Mannequin system where you can put gear on the mannequin (which also takes it out of your inventory so it doesn't use space!) and use the mannequins to switch between sets of gear at once. So in the future you'll just stick your DoM gear on a mannequin and switch to that mannequin when it's time to gear them up.

I'm not sure when it's supposed to be implemented but it should be available at the start of 2.0.
