Forgot to sneak this into the thoughts above before the edit timer ran out haha
This little snippet based off insights from this thread might be useful too since it is the method I’ve seen used to compile two lists values at the same index into a new combo list.
[" ".repeat(this.formula["Skills Compiled"].length).split("").map([ this.formula["List A"][index]]).map(this.formula["List A"][index]+[" (" + this.formula["List B"][index]+")"])]
I was only barely able to wrangle it for another purpose elsewhere and tried not to question it too much after it worked in that instance, but to a better trained eye, maybe it offers a springboard.
