Virtual Thermostat - change (or not) Target Temperature to other thermostats

[AdyBOSS]

Hi,
I'm wondering if I do something wrong or it's a wrong behavior of the Virtual Thermostat so maybe someone can help me with the folloving.
My setup is as it can be seen in the below pictures:

• Room Plan (Baie - bathroom)
• One Fibaro Thermostat (radiator) - Radiator thermostat
• One Danfoss Thermostat (hardware) - RS-Z Sensor
• One Virtual Thermostat (of the app)

My problem is when I want to change the Target Temperature on the Virtual Thermostat and on that moment the Radiator thermostat's Target Temperature is changed too. I don't want to change other thermostats target values.
I managed somehow to avoid this with Flows and variables but I prefer to have another approach like in another version of Virtual Thermostat where it's and option to follow or change Target temps from or to other thermostats (in zone or subzone).
