Is there a way to keep a chore open ended?

Is there a way to keep a chore open ended?  I have certain chores that we do not want to have to assign a specific time to do.

At this time, you cannot leave a chore completely open ended, but you can have it repeat without an end date. 

To do this, leave "End Date" blank when you are creating and assigning a chore. You will still need to select either a daily, or weekly occurrence, but if you leave "End Date" blank they will repeat indefinitely.
