Generate multiple binary files on ISE with different serial number

I want to version all the boards on which I put a version of my FPGA. Each board shall have a different serial number stored in an internal ROM. It's basically a 10 digits number (ie: 0123456789).

After generating the binary file , how can I modify it to increment the number without damaging the FPGA and its behavior?

Have anyone already done this before?

Which FPGA are you using? For Xilinx Devices you can use the USR_ACCESS register that can be set when creating the bitstream file. Limited up to 32bits of data. https://www.xilinx.com/support/documentation/application_notes/xapp497_usr_access.pdf
