I don't know if it is possible with Potlatch to put relations as members 
of a relation. It is quite easy on JOSM.

The schema of a relation type=route including relations type=route is 
widely used on this program :
http://wiki.openstreetmap.org/wiki/WikiProject_Europe/Long-distance_paths
It is a way to split a very long route into several parts as for
http://www.openstreetmap.org/browse/relation/138227

If only parts of other routes must be included, the ways can be members 
of several relations.

Some use a type=superroute for the main relations, but it is not an 
existing type and it is not necessary for the route is simply a route 
even if members are relations.

There is a good map showing the routes and rendering the osmc:symbol :
