Please add the quantity of extras in the variable %service_extras%

In the notification mails I can't add the quantity because there are so many extras for each service for this website and each time something changes I have to check al these variables again and the mail looks really unprofessional.

Workaround for now is that all options are split up, but this is not really user friendly for clients. (see screenshot)

Example:

Extra's:
