Post Slug with Event

I’m trying out event as a replacement for MarketPress in posting paid services. It’s putting my new events in this directory:


Is there a way to change this? Or will it default to a year/month/evenname scheme?

Partly asking because if I’m posting a March event in February, it makes more sense to post it in a folder labeled 03 — also, some events are ongoing, (you can add more than one date per event), so it doesn’t make sense to save it in a folder that specifies a particular month.
