What more can be done with Trajectories?

[MetalUrge]

Can we do the following with Trajectories (animation):

 

1) Edit the trajectories like how we edit a spline (with bezier for example) so that the animation positions are altered accordingly?

2) Make an object's trajectory follow/match another object's trajectory?

3) Assign multiple trajectories to an object by its sub-objects?

 

My questions may mean no real significant purpose but I do feel the requirement sometimes.

 

All in all my questions yearn to understand what all can we do with Trajectories in 3ds Max apart from the dotted redline we see in the viewport. Are there any good threads/tutorials speaking in more detail about them?

 

And how do the Trajectories feature in Max differ from those of any other softwares you know of?

 

I tried searching on Google but found absolutely nothing.
