camera tracker presets

When I use the camera tracker in Fusion (or resolve) , there are some film gate presets to use. Is there a way to add more presets there, or do I have to make my own tool presets to have my regular cameras handy? Maybe a text file with the original presets that can be altered-modified. Thank you in advance

I too am interested in this.

Hate having to adjust the focal length and aperture size everytime
