exclude certain packages from update in Satellite

Does anyone know how to configure a system in the Satellite so that it never receives updates to a given RPM(s)? This is pretty easy to do with YUM in /etc/yum.conf using exclude=, and I even found a way using RHN with the registration wizard (https://access.redhat.com/site/documentation/en-US/Red_Hat_Network/5.0.0/html/Reference_Guide/s2-software.html#fig-registrationwizard) but can't find any way to do this using the Satellite.
