Can I filter a page collection by available language translations?

On the documentation, I see there are lots of ways of filtering/sorting pages in a collection (taxonomy, date, etc.). Can I add a filter for available language translations?

For instance, I would like to show only a list of pages with an available translation in Spanish. Is that possible using collections? Thanks!

Thanks, that got me going! I might try to see if I can code a pull request so a sort of "no language fallback" feature for page collections can be included in those defined in frontmatter, to avoid the need for Twig/PHP for this filter.

Thanks again!
