Automate daily interface of gltransrel files from ftp server

I am looking for information on how to automate the import of multiple interface files from our Lawson ftp server into the gltransrel table.  I am looking at the importdb utility, but there does not appear to be a way from that utility to import multiple files in a single pass.  I would like to have Lawson make a daily, or even hourly pass through the ftp to pick up any files that are out there.  Can a recdef job be defined here possibly as a solution.
