Hello, I'm trying to set up my Hellknight character sheet, and need to create a new attribute hellknight_feats and hellknight_class_feats that counts how many class feats have the "Armiger" Trait and also counts how many total feats have the "Armiger" Trait. I intend to have hellknight_feats = @{count_all_feats_by_trait|Armiger} and hellknight_class_feats = @{count_class_feats_by_trait|Armiger} Is there a built in way to call a function like this? Thanks!
