Creating a .rbf from a combined .sof and .elf

I can create a .jic file from a combined .sof and .elf by first converting the respective files to .flash files then converting the .flash files to .hex. When .jic is the output you are allowed to select multiple .hex files which get concatenated together. This isn't the case with a .rbf file, at least as far as I can tell.

The board includes a cyclone IV with and embedded NIOS, and a completely separate microcontroller that has direct access to the SPI flash that the FPGA uses as its configuration flash.

In previous design that didn't include an embedded NIOS the external microcontroller could download the .rbf and program it directly to the FPGA's config flash. I need to be able to do the same thing except with the added complication of needing to include the NIOS image as well.

Anyone have any idea on how to accomplish this?
