Sync local files folder(s) to "My MP3"

So far, the only way to use MY collected song library is to upload them in Deezer via PC Deezer. OK. But can we have a feature to make this more easy to update ? Have a "lookup folder” that will be checked and new files added to “My MP3” on Deezer.

Thanks

I buy music from different sources on a regular basis since years, all stored in one giant Music folder (because of streaming services), that’s thousands of songs, impossible to check manually if every song as been transferred with success.
