You do this in Tools -> NoteTracker by adding a filter in the Player section. The filters you're interested in are in Hand Details -> Player Position. Due to the way this works though you'll need to use a lot of and/or statements to build this particular comparison as you want all of the times the Player is in position X and the 3bettor is in position Y where Y > X -- so you'd add Active Player exactly 0 by itself (you're always IP on the button) OR (active player exactly 1 and 3bettor >= 2) or (active player exactly 2 and 3bettor >= 3) OR ....

this tutorial for more details on how to use our filters system.
