Sure, that is a limitation of this simple feature. But I do not see how 
one could sort a branched two-way route relation into a linear list.

Since multipolygons are often nested, it would make sense to group those 
in nesting order. But then such groups should be marked in the relation 
editor, e.g. in a tree structure. Maybe this can be implemented in a
