I saw one around somewhere but I can't find it now. Here's a bump so someone who knows can maybe point you in the right direction.
I was working on adding VCs to my National Objective charts (linked in my signature), but I haven't gotten around to it. I haven't really worried about it because of the six Global 1940 games I've played none of them have come down to VCs; the Axis win is always pretty clear before we actually get to that point.
Edit: Found the one I was thinking of (fifth post down): http://www.axisandallies.org/forums/index.php?topic=22019.msg738513
