Nag an approver?
Is there a way to send a repeat approval request if the initial request goes unanswered? Kind of like a, "while 'Jane Q. Ceo's' approval status is 'Submitted' send an update request once a day."
Then, of course, once it changes to approved or declined, the notifications stop.
It seems like all of the notifications or reminders activate when something changes, not when it stays the same.
