For somebody to take a crack at it, you'd first need a list of the names and inline roll formulas for each of the checks that you want included, using Starfinder sheet attributes, etc. I included a snippet from GroupCheck for the 5E by Roll20 sheet for reference (starting at line 512 in the one-click version). I'm sure there's more to it than that (I just skimmed the code for a couple minutes), but it's for sure a prerequisite. "5E-OGL": {
