Is there any way to automate an import using Node Import? Ideally, I would like to be able to drop a file in the imports folder using a predetermined name, then periodically (say on the cron job) it will import the file using pre-stated configuration options (rather then having to use the import wizard manually), finally deleting or renaming the import file ready for the next one to arrive.... in other words in import workflow so that I can hook my site into another system that will feed it with new node data....
