Use regex in path to match subdirectory?

[zd-project]

Looks like the loadPath only accepts string or lookup function and the interpolator only populates language and namespace option. There seems not to be a way to match files in subdirectory via regex. I'm wondering how to elegantly handle look up in subdirectories since I would like to organize my translation files into subdirectories rather than putting them all into one big directory.

We personally use /locales/{{lng}}/{{ns}}.json -> everything outside that can be done using the function which gets lng, ns -> every other structure you need to get yourself
