I've been looking at some floor truss layouts and it appears that within a given truss set or assembly the chase will line up across multiple spans as I have shown here:

Generating a new truss component for each separate span is not too difficult, similar to generating a new step down hip truss component every 24". One thing to note is that a polygon outline will only work for floor trusses if the angles are all orthogonal, at least the bearing walls where the trusses terminate.
I'm a little unclear how to deal with the ladder trusses at the transition between different spans, perhaps someone has a 3D model or pictures giving me some clarity in these areas.
It took me about 15 minutes to create this complex floor truss set using the rectangular floor truss tool (3 separate truss sets) and the trim tool, not terrible but it would be so much better if I could achieve the same result in a matter of seconds with no manual editing.
Cutting holes in the floor and having the hole cutting tool able to regen the proper trusses is also a hot item related to this discussion. That would make the floor truss feature actually functional as a real world design tool.
Another issue is multiple chases within a truss set. One central chase seems the most typical but two chases positioned within the central third of the truss span also appears to be quite common. So far I have not seen more than two chases in a given floor truss span, probably for good reason. The ability to create two chases rather than just one is now on the "todo" list.
