CRELoaded osCommerce EasyPopulate Automation

Not sure if this can be done, but we'll see! The goal of this project is to have EasyPopulate in our CRELoaded osCommerce store automatically check to see if a file is in a certain folder, add certain column headers, add "EOREOR" to the end of each row, save and then import the new file. We have a system in house (SCO OpenServer) that we export a spreadsheet from using the report writer. It exports feilds depending on the report we want generated, in this case being item number and quantity. We have this file set to upload to our server hourly. We want osCommerce to open, add required feilds, save, and automatically import this file when it's done. Let me know how we can do this!
