I also wanted a way to invoke one command and get ssh connections to multiple pi's - in my case 25 of them (crazy, I know). I did it using "screen", a quirky but powerful "full screen window manager". This is probably not what you're looking for, but it might be an acceptable solution for someone who googles this topic and doesn't mind using screen.
Two ways of doing this - one with and one without a "regions" file - my terminology.
I have attached my screen configuration file (that defines what I want to ssh to), and which sources a "regions" file which splits a single terminal window into 24 regions, 4 across and 6 down, and which slots SSH sessions into particular regions. You go into a terminal and invoke it with "screen -c pi25A" and you'll get 25 sessions spread out across the screen in a grid. This works for me because I have a 32" 4K monitor and I can make the terminal window fullscreen AND set the font size very small and still read it. NOTE: I use ssh-agent so that I don't have to enter my password 25 times!
If you remove the sourcing of the regions file, you'll get all the SSH sessions stacked into one terminal window, on top of each other (best way I can describe it), each then taking up the whole of the original terminal.
In either case, there are hotkeys defined that let you move around in the many sessions.
Yes, I know 25 sessions don't fit into 24 regions - I've bought one pi too many and I haven't bothered to define a regions file with 5 regions across and 5 down.
edited for a typo and to add the note about ssh-agent...
