Hide DFF Contexts in SSHR

 We are currently using the Add'l Period Of Service Det's DFF to capture data about an individual's rehire eligibility based on termination code using different contexts.  We have had to change around some of our termination codes.  We have end-dated the codes in the LEAV_REAS lookup so the actual codes are no longer displayed in the termination reason LOV.  However, the contexts that are associated with those termination codes are still needed so that we can view the data historically in the PUI.

In the PUI we synchronize Leaving_Reason and the DFF via the provided refernce field and synchronization seeded functionality.  However, in SSHR this functionality doesn't exist so the users must manually select the context.  We don't want the users to be able to select the context associated with the end-dated codes, so we would like to hide them.  I have found that you can  configure what is displayed in a DFF in SSHR by personalizing the Flex Segment List by entering:
