Imagine instead of having your staccato strings, your legato strings, and your sustain strings on 3 different tracks, they could all be on 1 condensed track.
I write for film and I have about 200 tracks in my template. A lot of these tracks are the same instrument but different articulations.
If we could route each articulation into one instrument track and then in the instrument track you have a time ruler where you can select which articulation you want from measures 1-4 for example, and then switch to another articulation from say 5-8, all on 1 track!
Cubase has this feature. And for film composers this is gold.
