Can I import a collection to a collection

I have two collections for a set of hotels. One is in English the other in Spanish, same hotels so they both have shared data eg pictures, lat, lng. So, I now realise that I should just have created the one collection and output the page via two templates, one for Spanish and one for English.

Is there a way to merge these two collections from hotels-es and hotels-en into just hotels?

There are only 18 hotels, so it's no big deal to manually redo them. The import function does not appear to list other collections as an option.
