I have your standard intake form that I use to populate a workflow with business process variables. Within that, I have a proper set up for a pdf fill out activity that maps correctly manually. However, every time I try and tweak the pdf and update it on the server attachment, it drops it's field mappings. I've been able to deduce it can be something as small as a character change that causes this, since workflow then sees it as a new pdf, yet it holds onto radio button groups for some reason. The screenshot displays this.

My question is, does anyone know how to do this automatically? My research seemed to indicate Assign Token Values could be used to create a new token with the Adobe field name, and it would match that way but it still dropped it. The other options were a small xml field file, custom scripts, or a token dictionary. I'm just trying to figure out the best way to do this that doesn't involve heavy scripting. Thanks!
