(This is not a 3-way circuit set up.)  I have two seperate circuits, each with their own Kasa HS220 dimmer switch on them to control two sets of LED undercabinet lights.  I'm trying to find out if there is a way to group these two switches together so that when I manually adjust (turn off or turn on, or adjust dimness) using one of the switches itself it will also have the same effect on the other Kasa HS220 switch?  I know I can group them in the App so that when making changes from the App, it will effect both switches but trying to find out if I can extend that grouping so that manual presses of one of the physical switches also has same result on other switch.
