Reuse a Session with multiple hosts

I have defined a couple of sessions that have proxy settings saved, but no end host. I would previously load those sessions and type the different host names that are on the same end network.

Now with 5.5 I'm not able to type a host name in those sessions, it looks like right-click "Clone to New Site" is what I have to do for the equivalent? Is there any way I can make that the default behavior on double-click?

Thanks for your suggestion.
