FCP default audio/video sync settings

I've done a shoot where I shot audio and video separately, using a MixPre and a 360 camera.

I want to sync my takes, but the clip settings always default to the audio source (720p). But its a 360 8k video, so it takes me 4 clicks to set it right everytime.

We have 85 takes in total. I can't believe there isn't a way for FCP to use the video clip settings as default.

I've tried selecting the video first or last before clicking "Sync...". I've also tried using Custom settings, and it always reset to 720p (my audio clip setting).

Is there a way to change that? Can I remove the video property of my audio clips?
