I like to set annual reminders for items that I am responsible for ensuring has been completed, but I do not complete the task. The person responsible for the task tracks their tasks using different software (e.g. Ensure Annual Racking Inspection completed).
I want this to populate on say the 8th August every year, but when the reminder comes in my list, I may need to chase it multiple times until completion. So if I change the due date, once completed the auto recurrence will set for the last due date of the task, not when the inspection is actually due.
