Howdy folks!  I'm new to the forums and to doing anything custom with Roll20, though I've been using the site for years now.  I am hoping that the community can point me in the right direction as I'm beginning a new game and find that the extant materials (that I'm aware of) don't seem to do what I need.  I'm running a superhero campaign in BASH (Basic Action Superheroes), and there is already a great BASH character sheet, which I've used before.  My trouble is that the default BASH system, for which the sheets are designed, use multipliers and 2d6 rolls as their mechanic, and I want to run it with the alternate rules, in which the multipliers are replaced by just d12 dice pools.  Can anyone recommend resources that do that, or can anyone point me to tutorials that will show me how to modify the existing sheets?  Is there another option that I'm overlooking in my ignorance? Thanks guys!
