Triggering device reconfiguration from inside a Stratix IV?

Is there a way to trigger a Stratix IV device to reconfigure itself from an active serial (EPCS) device without using an external CPLD to toggle the reconfiguration pins? I know there's an ALTR...

This is an existing board. There is a way on this board to drive nCONFIG from an external CPLD if I have to, but it's kind of a hack. If I could do it purely from internal FPGA logic, that would probably be cleaner.

What would be wrong with getting the CPLD to do it? At least the CPLD can guarantee that it asserts nCONFIG low for the required minimum time. I wouldn't see it as a hack.
