[Feature Request] A feature that auto tags per the uploading user?

[Daemonias]

Is your feature request related to a problem? Please describe.
My Partner and I use Calibre-Web to Sync our E-readers and use the same library as to not have to install two instances of Calibre-web. To seperate our books we use the "allow/deny tags" feature. But that means that every time we upload a book we have to add a tag either too the new book or to the list.

Describe the solution you'd like
A option to have CWA automatically tag any uploaded Book with the username of the user uploading the file in addition to any other tags.

Describe alternatives you've considered

The only alternative is to go into every uploaded book and manually add the user tag.
