Hi Michael,
it turns out there was already a very similar feature request (actually for an even more powerful and flexible implementation than the one I proposed).
http://help.locusmap.eu/topic/statistics-for-segments-on-a-track-%E2%80%93-statistical-data-between-two-arbitrary-waypoints-on-a-track
So I just added my vote there, and linked this post in further support of the case :-)
