Tado heating supply temperature

Hi,
I will be installing floor heating in the near future and was thinking of partially running this from HA. On the first floor we have standard radiators so I thought it would be interesting to alternate between two different supply temperatures. I noticed that Tado added this to their app but it does not seem to appear in HA.
Does anyone know if we can reach this setpoint somehow.
Below a screenshot, it is in Dutch, could not find how to change the language.
