I want a way to change Device Individually Controlled from within Home Assistant

I am having an enhancement request.
I am facing a challenge with the Mill integration. I usually use the Mill app to schedule the settings for my Mill heaters. Previously, I had set it up so that when the door sensor on the veranda door indicates that the door is open, the heater turns off. When the door is then closed, it should return to the Mill app’s scheduled settings.
This system worked previously, but not anymore. Now, the Mill app indicates that the heater is individually controlled, and therefore will not be controlled by the Mill app. Based on what I have observed in Mill’s API, it seems possible to change “controlDeviceIndividually” to “0” to disable individual control. I am therefore wondering if it is possible to improve the integration of Mill in Home Assistant, so that we can change the heater’s status from being individually controlled directly from Home Assistant?
