Cinematic Tools, Can't render 4096

V. 4.14

In the Details tab of the Cinematic Camera there are some presets. None of them will give me 4096. 3840 is the standard for TV and other media for 4K 16:9. But I want to render out to the one of the 4K DCI standards for digital projection in theaters which can be up to 4096. Even if I set it to 4096 in the Render Movie Settings, it obviously tops out to whatever the camera setting is which tops out at the DVD 4K 16:9 standard of 3840. The Custom setting in the camera Details tab does not seem to work. Is this a bug?

EDIT:

OK I got custom to work. Forgot to expand the arrow so I can enter custom numbers. Thought you could select custom from the menu. Would be good though.
