Add Project column to Purchase Order screen / filter POs by project Number

As per the title, there doesnt seem to be any way to search for purchase orders by project number (other than running a report, remembering the PO number and then searching for that)

Obviously thats pretty rubbish way of finding them.

If a Column could be added on the PO screen, it would be posisble to group by Project number.

Also we need to be able to call up that field in filters
