Trajectory is a common feature of event calculii. I don't believe it would work with the 1.5.4 version using pre-processing, because it is not able to deal with situations where dates are being calculated from dates. I'm pretty sure trajectory would have that effect.
It's also not totally clear that it's necessary. It might be the case that we can do whatever we want to do without adding another block to the language.
