how to add listing with no street address

Hi – I’m just getting started with your plugin. I hope to use Open street maps, rather than google. My directory is for xc ski trails. Most ski areas don’t have a street address.

I’ve worked through the set up wizard and am trying to add my first listing. The listing page requires a street address and postal/zip code. Is there any way I can make it so a listing can be made with latitude and longitude info only, and remove the requirement to add a street address?

Thanks!
