It would be great if Zenmaid had a feature like this where it would tell you if you rearrange your clients in a smarter way you can reduce your drive time. That we could kick off every few months and suggestions on what date and when to place new clients.

Most of the data that they request at this site(myrouteonline.com) that does it is already collected by Zenmaid. The only thing I believe you would have to add is restrictions on clients on when they can not have cleaner come.
