Ability to add 4th Status field on shipment search screen

Hi All

I've a requirement where I need to build a saved query from shipment search screen and this needs 4 status types to be compared, however I see that there are only 3 status type fields and don't find an option to add the fourth on the corresponding screen set. So, can someone comment if there is a way to do it or do we need to go for XSL customization.

Thank you in advance.
