In Adobe Acrobat forms, I could name a field. For example, I have the same 4 questions for several presenters, so I name them "Q1Session1, Q1Session2", etc. I have not been able to find this feature in Forms Central.
Just label the fields as normal. You can go into the response tab and change the headers (on top) to be whatever you want (you can make them more unique). Those are used when you export to Excel.
I think that will solve your problem.
