Automate Temperature with AVM DECT 301 Thermostat

Hi all,

i am currently running a set of eight AVM 301 Thermostats. So far it is working with the limited Smarthome functionality of AVM.
One disadvantage is that you can only two different temperatures where the automation can switch based on time of the day.

But my wife wants to have a higher temperature than the default one in the morning for an hour or so.

So the main question is how can i set an individual temperature on these thermostats?
I can only find automation switches for the two predefined modes (eco and comfort) provided by AVM.

Thanks
