Yes. The url method of CatalogAwareness does this. So you could just add
"url" to the metadata of your catalog.

It makes it less efficient, as the object would have to be obtained when
you made the brain.url call. Not much point using brains at all then.


Although there are ways to do this now, I guess I was wondering about
making it a standard part of catalogs.

Thinking further though, if it is as easy as adding "url" to the
catalog's metadata, why bother?
