more than 4 ir controls?

[Vanquish]

Is it legal for us to set multiple actions to our remotes or is the limit 4? We were thinking of if you hit the button once, it does one thing, if you hit it again it stops whatever its doing, etc.

button 1: fwd, hit, stop, hit, rev, hit stop
button 2: right, hit, stop
button 3: left, hit, stop
