Quick question: how do I set a custom slug for a course?

Hi,

Quick question: how do I set a custom slug for a course?

I have for example a course called "Behavioural Science for business - Managers", which appears at a url like "http://courses.sodak.co.uk/courses/behavioural-science-for-business-managers/".

I'd prefer it to be listed under a course code, something like "http://courses.sodak.co.uk/courses/cem001/", but I can't see anywhere to edit the course slug manually as I'd do for a normal WordPress post.

Thanks,

Chris
