For Discovery display labels (labels in Primo), all work order types (fulfillment, bindery, and acquisitions) are controlled through the following two customizations:

1) c.uresolver.getit2.itemlist.status.WORKORDERDEPARTMENT.
withexpected_date In process of {0} until {1} (where 0=Work Order Type, and 1=Work Order Days to Process)

2) c.uresolver.getit2.itemlist.status.WORKORDERDEPARTMENT.
withnoexpecteddate In process of {0} (where 0=Work Order Type)

So, currently, we cannot customize down the the statuses setup (local to us) under the work order departments, but this would be helpful to do. For instance, we have fulfillment work orders with a status of Trace Requested, for items that are lost and being searched for, but that are not yet declared Missing. It would be helpful if the message displayed in Primo could indicate that the item was being searched for, and didn't merely display "In Process of Fulfillment."
