How do I start an SSH session from the Unity desktop with arguments (-i)?

http://askubuntu.com – Using SSH in a GNOME terminal is fine. But I want to use it in a Unity window (the location text field, ctrl+l). I need to refer to my .PEM x509 certificate for security reasons to connect to my Amazon aws EC2 server instance, by using the -i argument that I use in the terminal command. In the terminal it looks like something like this: sudo ssh -i mykp.pem ubuntu@ec2-something..etc.compute-x.amazonaws.com GUI window: ssh://ubuntu@ec2-something..etc.compute-x.amazonaws.com.....??? Thanks in advance for any help! (HowTos)
