Filtering Fulfill Orders Page

I went live with netsuite last week and im running into a slight problem with fulfilling, and im wondering how other people are handling this situation.

Let me preface this problem by saying that we ship most orders from our warehouse, but our business also dropships orders from other suppliers directly to our customers as well.

My shipping employee operates out of the "orders to fulfill" page all day. Its how he knows what orders he needs to ship each day.

Right now, When he loads up the "fulfill orders" page, he sees any orders that contain any items that are not fulfilled (including items that we dropshipped). I dont really want our warehouse shipping guy to see items that we dropshipped from elsewhere on his "orders to fulfill" page. I only want him to see items that need to physically ship from our location.
