Hey bradsperr,
Glad you like the plugin!
There isn’t any easy way to do this currently. There are plans for several improvements over the next updates as far as customizations of the form. There will be some hooks for developers to use for situations like this as well (but this may take some time).
You can edit the source code to do this in the mean time. The file inc/form/class-rtec-form.php contains the code that outputs the html for the form and fields.
Definitely not ideal though but hopefully it will be in the future!
