Storage of left over pellets after cook

Hello all:
I got a 640 in mid July. Have done two cooks - 1. Alabama chickens 2. Ribs and a 10 lb Pork Shoulder. Both cooks turned out great. I really love this cooker.
My question - after a cook what do you do with a half of hooper of pellets that are left over? Do you leave them in the hopper until the next cook or remove them an store in a plastic bag?
Thanks
Jeff
