Skip over "To Receive and Bill" when creating a new Purchase Order

Is there a way to skip over the “To Receive and Bill” status when creating a new purchase order?

Also can we choose the PO status when creating a new one? I tried to uncheck the read only box in the customize menu, however, I get the message “You cannot unset ‘Read Only’ for field Status.”

Thanks!

I ended up using a workflow.
