How best to track Group Resources?

I'm running a game of Pugmire, and one of the Resources there for players is the Fortune Bowl, which is a shared resource. I'm looking for ideas on how best to keep track of it, across maps and everything.

Follow these steps, in this order (the last step must be performed last!). Create a character, call it Fortune Bowl. Set Edit Permissions to all Players, leave Visibility to none. Give it an Attribute called Fortune. Create a token, link a token bar to the Fortune Attribute Set the token as the default for the character. Now you can drag the token on to any map, and players can add or remove points from the fortune bowl by modifying the token bubble..
