Only allowing the selection of lists from the trigger record in the “for each item in list… do…” action is very limiting. Extend this by allowing the selection of a list from another step. Example, Step 2 could be “find a record” which returns a record with a collection of some sort. We would then be allowed to select Step 2 in the “List” section of “for each item in list… do…” and select the collection attached to that record to loop through.
This seemingly small change would greatly enhance workflows, even allowing for emulation of more sophisticated conditional logic.
