Having spent quite a while experimenting and learning, a process that is not yet complete - especially learning, rather to my surprise I have come to like Sets.
Over the last few days I have spent some time tidying up my Displayed placemarks. Deleting stuff, converting paths to routes where appropriate and generally making it look quite smart.
I went so far as create a Set called 'Local Routes'. I then attempted to copy a route into that set. Indeed it did just that except it copied the route as a series of waypoints which was not what I was expecting

So am I doing something wrong?
Is there another or better way of achieving the same result?
Could Sets be enhanced to accommodate named Routes and in the same way specific tracks? (I am guessing it would depend on the ability to nest?).
Really not urgent.
