You would have to write custom code to do this. I don't have enough knowledge of PHP to help; but, since you have access to all of the source code for Machform, if you know PHP, you could try to repurpose the code Machform uses to export data as Excel or CSV files (I can't tell you where to find it, but it is there somewhere) and create a new PHP function that will export the files to a network drive that is run by a cron job.
