Export a filtered Ticket list with the Contacts AND their email

Hello,
One of our users on a separate instance wishes to export a list of tickets that were resolved by a specific resource and then have the contacts (we use contacts internally as the recipients of the tickets) but also have the Contact email adresses in said export 

This is to be able to have all adresses and be able to contact them all at once
However, in Screen Customization, the email is just a varchar that can't seem to be referenced somewhere else and I have not found a way to add it to the tickets
This would also help when we need to contact the recipient without going into another screen every time

Thank you
