  • Issue of the topic: setpoint placement in UI

normally all setpoints independly of corresponding item groups are placed in sitemap file.
I would prefer to have setpoints inside the correcpondig item group.

Example: setpoint for room temperature in sitemap
Setpoint item=Heating_SW minValue=18.0 maxValue=27.0 step=1.0

I have a item group Heating and I wish to display setpoint in this Group not in main menu.
Is it possible please ?
