Maintain validity dates for FF assignements in decentralised FF

Dear GRC AC experts,

I am configuring decentralized FF with sw GRC 10, SP level 11.

If GRC admin wants to extend the validity date for FFID in plugin system (SPRO->GRC->AC->Maintain Validity Dates for FF Assignements (Plug-In)),

the application displays only user ID and roles that have expired firefighter assignments.

My question is - is there any possibility (e.g. conf. parameter) which could be set and that table will display the complete list of every FFID in the system no matter they are valid or expired.

I know it is possible to view the complete list of FFIDs in GRC (master) system. For our GRC admins it would be more convenient to see

the complete list in plugin system (while he is maintaining validity dates).

Thanks.

Ivana
