This would be  BUG#5179

You'll need to do a Apache::lonnet::restore() to get the current problem
state information for a particular student/symb.

Then (looking at the document loncapa/doc/datastorage)

                    # url to use to grab the file that was used for
                    # the submission

                    # filename of the upload file that is to be used
                    # for the submission

                    # comma sepearted list of student portfolio files
                    # for the submission

Are the fields in the hash from restore() that have the info that you

lonnet::filelocation() will take a
 /uploaded/domain/username/portfolio/.... url spec and turn it into a
 local filesystem location.

lonnet::repcopy() can be used to make a local copy for the file come
into existance (it fetchs it properly from the library server). So 

if (!-e $filelocation) { &Apache::lonnet::repcopy($filelocation); }

should bring it around. 

Need anything else?
