Showing more than 25 products in Marketpress admin

I know this is going to be a simple answer, I've searched around for an answer...

How to I show more than 25 products in the Marketpress admin area.

We are importing 500 products and need a way of showing all of them to do some bulk editing and deleting. Just don't know how to get the system to show all instead of 25 products at a time.
