Can we name guests?

Is your feature request related to a problem? Please describe.
We want to share our collective with a few guest users. We love the "create a share link" option. But all the links are all called "Guest" so we can't tell who actually edited what.

Describe the solution you'd like
It would be great to be able to give each guest link a name. So instead of edits showing "Guest" they would show as whatever we called the link.

Describe alternatives you've considered
Guest users. But then the user needs to login and manage a password. The share link is great!

Additional context
Thanks for collectives, it's really an awesome tool.
