Yes, you put it in isolinux/isolinux.cfg
Then create a new CD.

Download the ISO image to a Linux Box, and then run this script
mkdir cd_image
mount -o loop -t iso9660 Nu-CentOS-BQ-3.0.iso cd_image
mkdir custom_cd
cd cd_image
cp -Rp * .discinfo ../custom_cd
cd ..
umount cd_image
rmdir cd_image
cd custom_cd

After you make all of your changes, now is the time to create an ISO
image. 

You need to have "mkisofs" installed to be able to do this

cd custom_cd
mkisofs -o ../Nu-CentOS-BQ-3.0.iso \
        -V 'BQ-CentOS Install v3.0' \
        -b isolinux/isolinux.bin \
        -c isolinux/boot.cat \
        -no-emul-boot \
        -boot-load-size 4 \
        -boot-info-table \
        -R -J -T .

That's it, it should create your new ISO.  From there, just burn it to a
CD!
