I am using a card button with Butler that does the following: for each checklist item in a named checklist, it converts the item to a linked card in list copying labels and members.
This works fine. However, sometimes I add additional items to the checklist, and I only want those new items to be converted to a linked card. So when I'm looking up the items in the checklist to converst, I only need the ones that have not already been converted to a linked card. Does anyone know how to achieve this?
