Welcome to MinistrySmart Online Community
You might want to consider using a Pathway for this. You can make one or more pathway steps, probably ordered steps, one for each item you need to have returned, then assign a step leader to keep track of the action item on each step and complete the step when the action is completed. Check out MinistrySmart - there's a great recorded video on pathways that covers this very thing. Sorry I can't remember the name of the course but it was fairly recent.
