Auto upload/copy a CSV file from Box Folder to Netsuite file cabinet Folder.

I have a monthly CSV file that is placed into Box and would like this CSV file auto uploaded into Netsuite File Cabinet where a Task import script will execute and import the data into the system.

Our firm has the Box integration setup and that works fine. I just want to automate the file upload from Box into Netsuite file cabinet folder. I can manually place the file into the file cabinet folder and my scheduled Script will import the csv file data.
