Single RGBW 'bulb'

Im trying to design a show utilising lots of Showtec Q4 Festoonlight.

I see The Chauvet festoon in the system currently exists but the A3D model reacts nothing like a festoon light should. Is there a way I can edit the existing model to make it react more realistic, or failing that is there a model/fixture for a singular RGBW lightbulb shape that I can use instead?

See image of current festoon light spread.

Thanks,
