Toggle Key Signal in Broadcast

Hi There

I have been trying to cut the key signal to black whilst a scene is running, whilst maintaining my fill signal.
The method I used was to disable Alpha in the render options node, shown in the attached file.
When doing this in designer and showing the key, the signal is cut as I would expect.
My issue pops up when running as a broadcast scene, the key signal instead of cutting, sends the RGB channels as a key.

Has anyone else encountered this issue, and if so what was your method for solving the problem?
Does anyone know a better way of removing the key signal, whilst maintaining fill?

Thanks

If one could access and animate the paramaters in the "mapping" section of the texture and then seamlessly switch between PMAlpha and Off in the target-tab...
