[Feature Request] Be able to change bed/tools target temperature

[JcMinarro]

What did you expect to happen?

I would like to be able to change the target temperature of the bed and tools of my printer.
It would be beneficial when it is integrated with some "Automation project" (eg: Home Assistant).
As an example, I would like to turn off the bed temperature when the print time left is below 10 mins. It would reduce the electricity consumption and help me to take off the piece of the bed.

What happened instead?

I only see controls to pause/cancel the print, restart the server and shutdown
