The Repeat task has customizable ending conditions, which allows it to act like a Do Until loop.  It would be useful to have the same ending conditions in the For Each task.

There are times when you want to run a For Each task until a certain condition is met, and no longer.  Example:  

For Each document imported today, find the one edited at 10:00 and then stop.

(And yes, you can do this with search syntax on prem, it's just an example.)
