Toggle Plugin Window (Show/Hide Plugin with one button)

Hello. I always have a VU Meter plugin in the 2nd insert of Control Room.
So, I assigned my Generic Controller to trigger the plugin to quickly access it.
(“VST Control Room”/“Control Room”/“Ins. 2 Plug-in Name”/“Edit”)

Now in order to close it I need to press another “Close All the Plugins” key, which also closes other opened plug-ins. Even if only VU Meter Plugin is open it’s not really convenient to hit another button to close it.

I’d like to press the same button again to toggle show/hide my VU Meter.
Is it possible to do it? If not I would like to request this feature.
