Are you in the discord? Folks in the #textmod channel might be able to help you make what you want. :)
I also made a tool for crafting custom spells, if it helps: https://docs.google.com/spreadsheets/d/1gOBoe9zA_CLVyUbZiJqcdWW-PXtVFlLj81FvrvMY...
I agree that while abilitydata is very cool, it's still a bit rough. Fingers crossed that tann adds more functionality in a future update. 🤞
