Yes, but it requires a little "hacking". I wish I remember exactly how, but basically it requires to create a bind.txt file. In it, you can specify which slots in the toolbar you wish to bind to specific key. Save the bind.txt file in the game folder.
Then in-game, there's a command you type in chat that references the bind.txt and uses for the game.
I know i've not been much help, but you can do it. For me, I've bound several of my powers (torp high yeild, cannon rapid fire, fire on my mark, etc) to a single key. I just have to tap that key a couple times and all my powers get popped at once.
