Proxy editing vertical and horizontal iPhone 14 video in Final Cut Pro

I have an app called ContentCam that shoots in vertical and horizontal. iPhone 14. Obviously this doubles the edit time. After I edit the vertical, is there a way to instruct FCP to proxy edit the horizontal? This is just for clips and transitions. Obviously lower thirds will have to be added manually.

Here are the file names that the app creates.

my_project_round_hoop__desk_clock_001_Landscape - Landscape file name

my_project_round_hoop__desk_clock_001_Portrait - vertical file name

Could this be set up as an action though automator......or pardon my longevity...a droplet?

Anyone ever attempted this, or want to try to figure it out when you can't sleep?

Cheers.

You can not swap out horizontally show clips for vertically shot clips in FCP automatically. But with the above instructions, you only shoot horizontal, then use that for both edits.
