[Help] Pathinfinder Group Initiative

I'm trying to set up Group Initiative for Pathfinder 2e using the Pathfinder Second Edition by Roll20 character sheet. I've got it so far to spit out the initiatives when a group is selected, but I want something more complicated. I'm trying to have the group initiative ask what skill initiative is based on and also trying to have the tiebreaker be two decimal places: the first decimal is 1/10 of the dex score (which I've done successfully) and then the second decimal place based off of a random 1-10 number to break ties within creatures that have similar dex scores. Any help is appreciated. This is the current closest thing I've got, but doesn't have the query and is missing the second decimal place: !group-init --add-group --Bare initiative|current --Tie-Breaker dexterity|current I looked around and maybe if I added an attribute to every character sheet it'd be easier but I couldn't find how to do that either.

I don't think there is a way to do either of those things without modifying the script.  I'd need to add an option to add the random .00–.09 to each roll for the random tie breaker value.  For querying, I'd have to add an argument you could pass in at roll time that would let you specify an attribute to look up on each selected creature, and then you could supply it with a roll query.
