(sorry for the late reply)

in simple.el you'll see:

(make-variable-buffer-local 'next-error-function)

so you can set this function every time ioccur is run in a buffer and it
will get called appropriately locally for that buffer.  Most modes have
a global binding for next-error-function but yes, you can bind it to a
lambda.
