Someone has recently claimed that Potlatch was a full-featured editor so 
I'm sure it must be possible ;)

Say you see a way in Potlatch which is a member of relation X (in 
Robin's example, the Auckland coast to coast trail), and you want to add 
this relation X to another relation, Y, which already exists (in Robin's 
example, the 'te araroa' trail).

* Select the way
* use "Advanced" mode to see relation X of wich way is a member
* double click relation X to open relation editor
* use "Advanced" mode to see relations of which X is member (currently 
empty)
* click "Add to" to add X to another relation
* since Y is unlikely to be already loaded, and thus will not appear in 
the list, click "Load Relation" and enter Y's relation ID
* Y is loaded, and X is made a child of Y.

In cases where Y doesn't already exist, use the "New Relation" button 
instead of "New Relation".

If you don't know the relation ID of Y, and don't even know an area that 
you could load to find it, then it is possible that you can use Google 
for that, searching for something like

site:www.openstreetmap.org  relation type=route route=hiking e6
