Urge Jar

Hi! I would like to know if I can use a single urge jar when working on multiple targets at the same time? Specifically, I want to work on not giving in to my overeating urges, which I want to use the urge jar for, but I also want to give up sweeteners at the same time (testing for a month). Should I use a single urge jar with 100 beads (for 100 urges) or a second one? Or one single urge jar with 200 beads? I don’t want it to get too complicated, so I guess a single urge jar is easier? Thanks in advance!
