Multi-Language Answers: Translating Entity Types

Hello,
I am working to build Answers in both French and Spanish, but the Search Configuration, including all entity type names are in English. Therefore, even with the translated word like “Heladeria” is a one-way synonym for “locations” no results are populated for this search. Built in entity type is a set as an NLP filter searchable field.

I am considering creating a new field for translated entity type name, and making this searchable as an NLP filter as well. I would make this field overridable per each locale. But, is there a recommended way to set this up for multi-language?

Thanks for your help with this!
