How to Install Multiple RPM's - Red Hat 6

I have some RHEL 6 servers in a disconnected environment.
I have a Repo server in that environment that I built based on this solution: https://access.redhat.com/solutions/23016
These RHEL 6 servers are built to specific baseline, so I can't simply run 'YUM update' on these servers.
Every few months I'm given a list of RPM's to apply to these servers.
What's the best way to accomplish this?
I assume there is a better way than manually installing each RPM separately on each server?
