That's not currently supported, and unfortunately, not something that will be added to BasicGrindBot. There's no way to enforce all uses of the Logout API to set an appropriate bot flag (which would be specific for BasicGrindBot), to make the bot go back to the previous area if you're chickening, and do actually want to return. In order to do that, we'd have to not run any user code, and use an entirely closed design for the bot implementation itself. It's the downside to the current setup of things; there's no real way to do things in one coherent manner, while still letting users change various aspects of the bot.
