Using LANC to control Return Video On/Off on a Studio HD/4K

I recently posted the following question to BMD support ...

Is it possible to re-direct the i.e. LANC REC command to the Return Video ON/OFF button on the Studio HD/4K camera, to improve the workflow for camera operators. Camera operators coming from OB are used to having the Return Video button close to the zoom/Focus controllers on the tripod/dolly.

Their basic response was that this was up to the manufacturer of LANC controllers to solve ...

Does anyone here use a LANC controller to control the return video button?
And in case of yes .... what product does this ?

Kind regards Nils M Alexandersen

Not likely going to happen or work. Record Lanc button only works with the Micro Studio to trigger a remote external monitor recorder like thr VA4K or a PixE. The Rec trigger signal is sent out the SDI output in the video signal as a marker to trigger recording off and on.
