In Manufacturing , is it possible to to include the custom Work order Status for Mass actions task?

1. We have created some custom work order Statuses in Manufacturing , now we wanted to include or enable these statuses in the Mass action task present on WO manage page , we can see only the seeded status are present their, is it possible to do the Mass action task for the NON-seeded WO statuses as user defined statues does not show in Mass action?
2. When any of the predefined status name is renamed , the mass action still displays the system status and not the new renamed name, why it does not show the New name?
