Nios II, interrupts and internal controller

Does any one know if it is possible to setup a Nios II, with internal interrupt controller using shadow register sets? And how does you specify what register set to use for each interrupt?

An interrupt entry/exit pair should leave the system in the original state - regardless as to the actual current register set. So you should only need to save enough state to restore the original set.
