Check out this recent reply to a similar question. The technique outlines there should select based on current mat or current cargo.
If you want the leader counter on the privat window to know about properties of the leader counters on the main map, make those two counters Attachments one way or the other. I do something similar in Littoral Commander: Indo-Pacific: The unit counters on the main map are associated with a tracker card on another map. When the hit points on the tracker goes to zero, then both the counter on the main map and the tracker are eliminated. When the resource count of Long Range Strike (LRS) - for example - hits zero on the tracker card, it is no longer possible to declare LRS combat with the counter on the main map - and so on.
