Export CPT linked Business

I was unable to find this topic via search and will ask here.

We are using CPT add-on with an extensive system of exports/imports. In the gd_place entity we chose to link it to a custom CPT (gd_vehicle) in the CPT definition of gd_place.

I add a gd_place post and choose to link it to a gd_vehicle item in the right column of the post edit. Display works fine and the links between are good to go.

Unfortunately, I have found that when exporting gd_place entries, there is no column indicating the relationship to gd_vehicle. More specifically, I need to be able to import gd_place entries including a reference to the gd_vehicle post id (or whatever the stored value is).

Does the export not include a CPT link?

Thanks

Tom
