Tranferring Character Appearance Data

So, I recently upgraded from PS4 to PS5 and I was able to transfer my system settings and character settings, however the Character Appearance Save Data didn't transfer with either of these.
To avoid confusion when I say Character Appearance Save Data I'm referring to the template players create that can be used to create characters and retainers without having to do character creation from scratch each time.
I keep these in case I ever want to change the appearance of one of my retainers or characters.

I was wondering if there is there an option to transfer this over directly or am I going to have to create extra characters/retainers for each of the ones I'm not using and do that to transfer it over indirectly.

And before you say it, yes, I know there is probably a way to do this on PC by going into the game files directly, but as I said I am on console so that doesn't help me.

I'm not sure if it'll work since I've never tried. But could you just buy a retainer fantasia off market board for like 1k, re-edit the retainer appearance and re-save how they look?

For active characters, you can right-click / press Square at the login screen to save their appearance.

For retainers, as Zotoh suggests, you can use a retainer Fantasia to start editing them, then use the save prompt that pops up when you've finished editing appearance. After that you can quit the process and do it again with another retainer, without needing another potion.
