you could set it up pretty easy, using the perform commands in your options, just, when you connect to the 1st network, have it do your nickserv identify and anything else, then at the end of that, add /server -m <server>, then make a tab for that server that does its connect commands, and have it connect to another server with /server -m <server>, and so on untill you get it connected to all the servers you need.
