In the Email Builder, currently, the "Preview" function lets you select a contact to see how the email will render based on that Contact's custom field values.

Testing requires one to go to the Contact, update the custom field, go back to the Email Builder, refresh the page, click Preview again, re-select the contact. That's a LOT of clicks and jumping around.

Can we please have the ability to test email rendering by updating custom fields inside the modal, eliminating the need to update a Contact's custom fields to see how things look?
