Creating posts with a "/" in the slug

Hi,

I'm trying to create posts within a space, and am struggling to see how to create a slug which looks like "<space>/<post>". I can see how to set a custom slug for things, however it always seems to autocorrect to hyphens instead of slashes (ie "<space>-<post>").

Is there a trick I'm missing please? I see it must be possible as the demos include proper url slugs.

Many thanks

Tobin
