Set actual temperature (not mode)

I didnt see an actual action to set the temperature of a thermostat… we can set the mode (I/II/III) but not the actual temp…

any idea is thats coming? or is that a signum/home assistant/openhab thing?

Just wanted to create an “away” button that I can tap once I leave the house… which switches all the AC’s to high-temp (or heater to cold temp) … without waiting for the program to kick in (as those as time bound)
