quick way to add new fwcluster to the install on field

[monks15]

I had to build a second cluster of two gateways for a site with an existing 2-node cluster. I need to add this new cluster to the 'install on' section of the rules that the existing cluster is also present on. I have about 500 security policy rules and a similar amount of NAT rules. I believe there is somewhere between 200 and 300 rules in the security policy and the NAT policy where I have to do this so I am hoping I don't have to go one at a time. Any suggestions? CLI or Smatconsole?

Usually, you use the Install Targets group in install on that you can change centrally. Otherwise, you are correct - but who would add GWs to install on manually in 200 - 300 rules ?
