Alliance troubles?

I'm really having trouble with the trigger making it so you can ally by typing "-ally color" Heres what i have so far:
Player one red types -ally blue as an exact match
make player one allied with shared vision to player two blue

Now, that works, BUT, that means i have to have 90 triggers like that! (ten players, 9 alliance triggers each). Is there an easier way for me to do this?

You could do a check for the substring. Then do an If/Then/Else in the actions. That would make it so you only need 1 per player.

Well lets just pretend im an idiot for a minute here, explain it in a bit more depth please.
