Can I make -ResolveDependency use another repository besides PSGallery?

When using `.\build.ps1 --ResolveDependency`, it connects to `PSGallery` to check for the latest required modules.
This, however, doesn't work in an offline environment. So I need to manually add the needed modules to each build system I and any of my colleges are using.

Is there a way that `.\build.ps1 --ResolveDependency` can use an alternative to `PSGallery` when in an off-line network?
