Allow customers to set ticket to solved in email notification

Hello,
Is there a way to add the option to solve a ticket right from within the status update notification that are sent via email? AFAIK, the only option for customers to set the ticket to "solved" for themselves is to check their request history and select it there.

Please add the option to have this in the notification emails as well.

It would also be helpful if customers could set a ticket to "solved" without any ticket activity. We have cases with customers who found a solution before we can reply.
