HEOS Multiroom - how to set the "group leader"

Hello, I have configured HEOS Binding and created a Multiroom group as well a an “Ungroup” Switch to activate the group. The configuration work as expected, except that I am looking for an option to set a group leader as it is possible in the HEOS App, depending on which room you move to which one.

Anyone around who has been able to set that up in openHAB?
