can someone explain to me the procedure to using the bubble revison clouds w/ triangles attached. Let say one sheet has 2 different revision. I bubble one and give it a triangle w/ number 1, and the second I give a bubble and triangle w/ 2 in it. Now I go to the next sheet, do I start over w/ #1 on that sheet, or do I pick up w/ #3? Just curious about what is the correct way to do this
