Tracking shared links via email

Hi everybody.
I’m using ownCloud 10.1.0.4 and I would like to track in some way, better into activity app, all email addresses used for public links sharing if I send the link via email using the built in function.
Right now when I share a link via public link in activity I see something like: “You shared DOCUMENT by public link”, I want instead something like “You shared DOCUMENT by public link with email@domain.ext, email2@domain.ext”.
Do you know if is it possible?

Thanks in advance.

Feel free to submit this as feature request in https://github.com/owncloud/core as it’s currently not possible and needs code additions in core. Interesting idea. cc @pmaier1
