Script that changes a multi-sided token across multiple pages

Ok, so an unusual request, and don't know if it's possible, but is there a script that will change a rollable token's side across multiple pages?  The Sprawl RPG uses several "countdown clocks" to show progress in the game.  I've got the countdown clock images, and what I want to do is have those clocks on multiple pages so that, if I change one's face, it changes them all.  Another hitch to this is that different clocks might actually use the same token (the Mission clock and the Legwork clock, for example).  Does anyone see a way to make this work?

Should be possible. You'd need to store the tokens as characters (so you'd have Mission clock and a Legwork clock character). Set the tokens to represent those characters. Then you use setDefaultTokenForCharacter to update the default token of the character when it's clock changes and then propagate that change to all other tokens representing the character. I'm actually doing this in the Pathfinder Companion that I am writing (almost ready to release v1.0) to update PC and unique NPC tokens across the whole game, so I know it's definitely doable. I might be able to whip up a proof of concept this weekend, it'll depend on how long prep for my monthly game takes.

JamesW has a script called  TokenSync that might do the trick. I don't recall if it handles token faces, but it syncs everything else across pages.

well, that is pretty much what I was going to do. Only improvement I'd make would be that you can also sync up the default token so that dragging that character back out will also create a sync'd token.

Hm...I'm not sure how to make it work.  I need to add a property, I guess imsrc?  But then it needs to not just sync the image source, but what side the token is showing - or maybe I'm not understanding how this should work.
