Ssh tunnel hosts changing...

I have a bunch of servers defined in pgAdmin that all point at a particular
ssh tunnel host. Well, the host that the tunnels go through now needs to
change, so I need to update all the server properties.

Is there some way to do that without having to select each server and then
properties and then the ssh tunnel tab? I had hoped that there would be a
disk file or directory of files for each server, that contained all the
settings, but then realize that the master password probably encrypts that
file/files if they exist.

Is there another simpler way to make this update to all (most) of my
servers?

Thanks,

Mike
