Unique SN's for production units - Quartus Programmer?

Has anyone used the quartus programmer in a production setting to apply a unique serial number to each PCB that is configured?

Any other suggestions on a good way to serialize units?

    You can write the serial number to a specific part of the programming flash memory, if you have a way to access it from the FPGA.

    I should add more details.

    The system has a NIOS and a UART in it, which I'm aware that I could write a routine to accept commands via a computer to the UART to program a specific value into an address in Flash.

    However, I would like to have this done while the program is being written to flash via the USB-blaster. Is there a way to have an incrementing number placed in one of the locations of flash memory, in addition to the standard program image which will remain unchanged?
