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?

I just wanted to get a fast interrupt respons with the internal interrupt controller, - without saving all registers. But as far as I can see, I only got the wrprs and rdprs instructions, - but no instructions to actually switch to a shahow register set during the interrupt processing. - Later in our process we are adding the external interrupt controler, and then my problems will be solved.
