Let members create their own documents

Question:
Is it possible to let members of the website (a.k.a. therapists) to create documents on their members area (a.k.a. patient records), store them and then be able to download them?

Product:
Wix Editor

What are you trying to achieve:
I’m building a website for a group of therapists which includes online booking. One feature they would like to have is the possibility to create patient records directly for their members area. It will have to be locked for each therapist (one therapist would not be able to see the records from other therapists).
And in this page, the therapist needs to see a list of previews records, edit and download them. Is it possible?

What have you already tried:
I don’t find documentation on this matter so far.

I think all information is added already
