Boost mode enhancement

First, thank you for the great thermostat, I'm still learning and tweaking the options and PIDs.

Regarding Boost preset.
I'd love to see it implemented like in other, commercial solutions, when activating Boost mode, it goes to desired boost temperature and after an hour or reaching the temperature goes back to the previous mode.

Of course, I can do it with HA automations but it think simpler and more elegant would be having it built in
