Include a custom ID/Tag in .rbf files

Hello,

I am looking for a way to include a custom ID in the generated .rbf files for CvP on an Arria 10 FPGA.

Essentially, one single byte at a static, fixed location would be sufficient.

The intention is to be able to verify matching files on-the-fly for CvP and hereby avoid broken constellations.

Are there any ways to do this?

Thanks!
