Each contact in these Eventbrite campaigns is automatically listed as 'Attending' in the Campaign Member Status.

I would like to update some of these to show who was a speaker at each event - however I cannot see how/where to edit the options available under the Campaign Member Status - so I can include 'Speaker' as a choice.  

(NB as an aside 'Attending' isn't an option that I can select either, but this is automatically set when the data is imported in from Eventbrite).

As an organisation we don't use the Leads module and, looking at old forum posts, my suspicion is that we may be here that we can update the Campaign Member Status options.  But if anyone can help point me in the right direction I would be very grateful
