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

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
