I am trying to modify the Maya camera's film gate attribute in which I have 2 almost similar film backs with the same values in terms of its aperture values etc but both with a slightly different naming.
For eg. the film backs naming are '35mm Default' and '35mm Delivery'

So in my current scene, it was set to '35mm Default' and I am writing a check in which it will pop up a drop-down list that contains 'Delivery' naming and user is to select the correct film back from there, in this case, it will be '35mm Delivery'

And so, my question is - how do I change such film backs/gates via coding? I tried turning on 'Echo all commands' but while it shows AEwhichCameraFilmback... it does not seems to have a variable that states the naming of the film back.

Can anyone kindly give me any advice?
