I knew about that, I used that to create the template files for both HTML and HTA that I need to work with our system. I was trying to get around having to do a double publish to get each file. I wanted to add a selection on the left side of the publish settings dialog for HTA files, like there are for SWF, HTML, SWC, PNG etc...
I was hoping the publish settings profile xml file would help me do that since all those selections are in there with their settings. But that was a dead end unless I did something wrong.
