Adding attachments to PDF form

I tried everything and looked everywhere and can't find the best solution to this problem.  I just need a way for the user to attach documents to a PDF form in Adobe Reader.  I have access to LiveCycle and Acrobat so is there way once the extended features are enabled for a user to add attachments to the form in Reader.  I have LiveCycle ES 8.2.1.  I guess the only possible way is when the user emails the form they can add the attachments then but I just want to see if it can be done by attaching to the actual form.
