Multiple fallback when a specific text is not found

[valim2322]

Hi there,
There is a way of fallback multiple times if a specific text is not found in a file?
Assuming that we have fr-CA.json, fr.json and en.json.
For example, I set the the language to fr-CA and I want to show "hello" in fr-CA. If the "hello" entry is not found in fr-CA file it should fallback to fr file. If the text is not found even there, fallback to en (that contains all the text). So fr-CA and Fr files contains only a set of translated text.

Thank you!
