Search "OHARP" or "No-cost TAD"...that should get you headed in the right direction. Yes there will be times in the training pipeline where you have a month or maybe even more of just waiting in a pooled status. You may have the opportunity at some point to use one of these breaks to go home, either on leave or no-cost TAD orders. In any case, the footwork will more than likely be yours, as most commands will find something for you to do with your spare time otherwise. It is entirely dependant on the specific command though. For example I have heard the guys waiting for 5-6 months to class up in Kingsville aren't allowed to do TAD, while many of us in Meridian got to do it while we waited to class up. Same thing for other locations, and it is normally dependant on how many folks are waiting with you (ie how many watchstanders there are with you gone), what your student control officer wants to let people do, and how much time you have to wait of course. But overall, it is entirely possible that you could do something like this at some point.
