Is it possible to PXE boot kickstart from first network and updates from another network from the Satellite server connected to these two networks?

Issue

• Have two networks currently associated with Satellite server.
• The IP bound to eth0 is for ssh, web access, and yum access whereas eth1 is for the private kickstart Deployment and DHCP.
• There appears to be an issue with how Satellite generates the dynamic URL value in the kickstart profile, when the URL value is overridden under Kickstart details - Advanced options it only appears to modify the first two instances of the repository server name in the kickstart file.
• Are there any other locations when one can override repo locations for the kickstart process?
