I am using existing "Meeting room booking system(MRBS)" opensource program.
In the present program, the admin's will get approve/reject request of all the rooms. All the Admin's are superusers and have access to all rooms.
room 1 has admin X
room 2 has admin Y
room 3 has admin Z
Current functionality: admin X,Y,Z can approve room 1,2,3.
In addition to one superadmin, each room should have one roomadmin. The roomadmin should get only approval/reject request only from that particular room. He should not have access to other rooms.
Required feature: Admin X should approve only room 1
Admin Y should approve only room 2
Admin Z should approve only room 3
