The best solution I've seen for this situation is to generate the Email Template in an external XML file as an HTML ... passing in the Variables needed to make it personable.
I believe I could look through my examples and find some for you to see if interested ... just send us an email to Support@GoAnywhere.com
and we can help you though this.
For your Feature Requests, those need to be emailed into the Support email address above as well, indicating it to be a Feature Request. We then pass it along to the Developers and (Hopefully) get it on the list as an enhancement to a future release.
