Listings without an address

I have searched through all that I can and can see that you can create a CPT that does not have a physical address but I can’t find any work arounds to what I am trying to achieve.

I am building a traditional directory using addresses however I want to add the ability to have listings which are basically POI – These do not have a physical address but they do have co ordinates. To be able to see these on the map enables users to get a better idea of what’s available within the area.

Is there anyway to achieve this – would GD be able to cope with this if a developer could take this up or is the structure unlikely to be able to cope with this.

In my simplistic terms I see it as a CPT with co-ordinates only. The title becomes the POI with other fields that may be required and the co ordinates allow a marker to point to the POI on the map.

Your views would be appreciated
