ARGeoAnchor: Supplement imagery in private locations

I am developing an iOS app intended to be used only a specific location (a campus). In this case, I'd like to use ARGeoAnchor to anchor content across a relatively large space, though in the pedestrian-only areas this is not supported and tracking begins to fail.

Is it possible to additionally use ARReferenceObject to re-localize to a specific location when I am walking in an unsupported area. (FB13719373)
