Control multiple devices with one element

Hello together.
I read some topics regarding control multiple devices with one control element but it looks like there’s nothing what would help me.
I had one device (LED stripe) with an IP address and want to add (in near future) a second one with an other IP address. So I copied my TCP plugin and changed the second IP. This creates than a second device with a virtual switch where I added the same attributes and capabilities. Now I should be able to duplicate my controls and connect them via device binding with the second device (e.g. VirtualSwitch.Color). Then I want to create a third page to control both devices simultaneously with one control element. I don’t know if there is a solution meanwhile since Nov. 2020 post where this was asked. I read “MultiBinding” is only for Labels.
My idea is to use the Data-Trigger funktion for the sliders of the two devices to make them dependent on the third slider for both devices. Should this work or is there a similar way?
Thanks and best regards,
Thorsten
