Spatial locations shareable between project files?

I have set up a model with several building stories defined in the spatial locations dialog box.
Now I want to share the spatial locations with a second model. What would be the best way to do this?

For now, I used a not-so-clean workaround: take the original model > delete/purge everything > save the empty result (spatial locations are preserved) > paste the second model into the empty file...
Any better suggestions? Did I miss an export function? Automatch? Bimify?...
