Not too likely. So far I am not certain that any of the timers are really working reliably, and the ones I have tried to write for myself have failed miserably. Not to mention that there are a LOT of things that can go wrong with casting Town Portal, so I would be more inclined to have an auto-route type of command if I were to go with a timer.
If someone else wrote it into the bot and it worked well, I'd be willing to incorporate it. But I just use the bot to multi-client events, not for AFK farming, so it isn't a personal priority (and I still have quite a few personal priorities to implement)
