Nucleus - Internal storage subfolder option

I have installed 4TB SSD drive into Nucleus+ and faced a problem with my library. My library is sorted into several top folders like JAZZ, CLASSIC, POP. Some of the albums are not tagged at all so I cannot search them by using genres, that is why I decided to use master folders. With NAS I could map subfolders separately one after one and then use inspector and storage location feature for create a focus for particular type of albums and exclude storage locations I do not need. With internal storage of Nucleus I cannot do so, because only one main storage is available. It would be a great feature at least for me if you enable to map subfolders of Internal Storage (like for NAS) instead of master folder, if someone decides to use this. Can you plan this kind of feature ?
