This is no problem at all. Basically, there are two sorts of contingencies, conscious and unconscious ones. You can solve any conscious contingency by just stating: 'X happens when I will it. Or Y triggers when I think of it'. There is no reason why contingencies are not allowed to trigger off a thought.
A bigger problem is when you want to trigger the contingency as you are being sneak attacked by that invisible rogue; the unconscious contingency.
