Is it possible to enable additional cooling for heat pumps using the API? #252

I have a 4th generation Itho WPU, with the MFT thermostat. This thermostat has the option to enable additional cooling for (by default) 48 hours. I've been considering using this option to enable cooling earlier in the day based on the weather forecast (e.g. enable it at 06:00 if it's going to be warm at 13:00), as the WPU has a tendency to be rather slow with enabling cooling (e.g. 12 hours after it gets warm).

Assuming this were possible somehow using the I2C bus, the benefit would be not having to flip the WPU into manual mode, something which I'd prefer to avoid as to not mess with the overall behaviour (i.e. I think it would also turn off the boiler?).

Is this something that could be added, or is it behaviour specific to the MFT of which it isn't known how to replicate it?
