Automate folder calling

I am currently using NBDEV to build a library and I have split by folders. NBDEV automatically populates these with init.py files.

Is there a way to automatically populate the init.py files i.e.

from .test import *
from .test2 import *

Or to specify specific classes to be included in init.py file i.e.
from .test import test_eq, test_close?
