[Feature Request] The ability to toggle a light trough the Gui

[patatman]

Is your feature request related to a problem? Please describe.

When I'm adding multiple devices (I'm migrating from ZHA), I have some devices that get joined at the same time. For example my hallway lights (tradfri) are on the same physical switch, so they joined at the same time. It would be nice if you could toggle the light trough the GUI to determine which light is which, so you can name them properly. Describe the solution you'd like

2 potential ways of implementing this:

• 1. trough a button on the overview page which toggles the light (or 2 buttons, one for on one for off)
• 2. After you openend the device, you have the option to make it flash (or simply on/off)

Describe alternatives you've considered

Currently this is done trough Home Assistant, but I think it would make more sense to keep the initial configuration with the GUI. Additional context
