Create a Loop option
For those who want to start and stop in the same place, you should create a loop option so they can see how far they could get in a given amount of time (ie. 5-6 days).
Thanks for the idea! It's interesting. I feel like you could get the same result, though, if you just divide your available time in half and plug that into the planner (since it should take the same amount of time going either direction). -Matt
