Ability to send list owner email message via reading list

For context, when we send list owners the "Review has been completed" email via the Reviews interface (the big tick mark), we let them know if we have left anything important Notes for Library against any items on their list that we would like them to read.

Beyond the review being completed, there are often other times when we update a Note for Library on the list and would like to be able to flag this with the list owner as easily, without having to compose an email to them in our mail client, copying over their list title (maybe even the link) and the details for item(s) in question. We're thinking a "Send Message" option in the drop-down menu when you press "Edit" at the top of a reading list that would automatically include the list name and a link to it, and with a field that you could put a brief message into. This would save us a lot of time!
