Automatically update products on MarketPress

Each night I get a .csv from the company I re-sell for. I would like to import this .csv automatically (as in batch) in MarketPress. Is this possible?

Ofcourse the .csv is not exactly the format MarketPress uses, but I can use PHP to convert the .csv into the format I can use on MarketPress. I'll use a cron-job for that part.
