1. Make Crates with the same name of your folder.
2. Import your Files in the Folders related to your Crates
3. Rename Genres if wantet ...
4. I do sorting my tracks right now. - Do not import all tracks at one time ! This will mess you up and drive crazy.
5. It's enough if you do not connect your Controller to ITCH and do a scan with "BUILD OVERVIEWS".
6. It might be a horror, if there would be an automatic sorting in the crate list, and you have to sort out the new tracks, to put them in somewhere else...
have a look at this :

Sort your Tracks by Genre, mark them, and do a Drag and Drop into a Folder.
This works well, if your tracks are tagged correctly!
