Voice memo app, which supports sub folders?

Good afternoon,
I’m currently in training to learn how to become more independent, as well as obtain skills necessary to get a job.
As part of this training, I’ve recently discovered how useful the built-in Voice Memos app is for quickly taking notes.
However, the one feature this app doesn’t have, which I’m looking for, is nested folder Support.
Does anyone know of an app which can record Voice Memos, And Support sub folders?
Synchronization would also be good. I have access to iCloud, OneDrive, and Dropbox.
Thanks in advance for any suggestions you may have.
