Calibration / zigbee curtain module?

Hi everyone! I am new here and this is my first post, I would also like to emphasize that I am just entering the world of smart home so please be understanding :slight_smile:.
In my new home I wanted to start with managing the roller shutters so i bought zigbee curtain modul and a hub (aeotec smart home hub). Pairing was easy but I can’t find anywhere the option to extend the opening/closing time of the blinds. some need much more time and the standard one is insufficient, which
means that some open 70%, 50% or even less.
I can only open/close/pause when selecting a specific device. When i select edit i only see the option to change the device name, location and room.
Do I need another app to calibrate or is there a different way to do it?
I will be grateful for your help!
