Advanced usage: copy not only files that are specified in 'main' section

[DV-ERDEDE]

Hi.

Is there a way to include not only main files from dependency?
I tried to use 'exportsOverride' but can't get files except marked as main. The values for dependency in 'exportsOverride' should be the pathes to files in dependency directory, right?
If is it possible, can you attach or show live example? The example for bootstrap-sass in 'Advanced usage' section doesn't work for me. Maybe it's out of date?

Thnx in advance.
