Enhance settings to allow the specification of which products will be exported

Hello,

I have a publishing house that I use to ship out books that I sell. They accept EDI orders. I have EDI installed on my site. The problem is that I also sell other products on my site that I don't want included on my EDI exports.

Pretty much, I would like to only have certain products be sent to edi export. On my site, people can order books and other products, and I am totally lost as how to only export the book products and "throw out" the other products when it comes to EDI. I've tried looking at the code, but I became lost very quickly.

Is there anyway someone could help me with this? I am willing to pay.
