Can I change the format of the buttons in the email templates?

Hi all!

We have been working hard trying to brand our email templates, and have some way to go yet.

One of the things we can't seem to edit is the green ${Cases.CUSTOMER_PORTAL_BUTTON} button and the font of the View Ticket text.

Is there any way of doing this please?

Cheers

Rich
