Restructure of Libraries possible without resetting watched status?

[yshi]

I currently have my library structured as such:

Media
>Movies
>>Anime
>>>720x480
>>>>Akira
>>>>etc.
>>>1920x1080
>>>>Ghost in the Shell
>>>>etc.
>>Children
>>>720x480
>>>>13 Going on 30
>>>>etc.
>>>1920x1080
>>>>Despicable Me
>>>>etc.
>>etc.
>TV
>>Anime
>>>720x480
>>>>Helsing
>>>>etc.
>>>1920x1080
>>>>Cowboy Bebop
>>Cartoons

And so on. When I first migrated from Emby, I'd mapped each category under Movies/TV individually, but there were issues, which I'd eventually determined to be due to a home recording sitting raw under General rather than in it's own self-named folder. At that point, for reasons I don't recall, I'd mapped the Movies directory to my movies library, and TV to tv.

Fast forward to now, and I'm rethinking the general structure, potentially the general categories, but mainly the resolutions, and would like to be able to disable categories for users that have no interest, which is only doable if I have multiple feeds in the library, AFAIU.

Is there a way to restructure my library, so that on rescan everything is still there (seeing as I'm only moving things around and not adding or removing media), so that all users will not have to go through and flag everything they've already watched as watched?

I'm guessing not, and I should hurry up and rip the bandade sooner than later as things will just get farther out of sync over time.
