Rebecca,
If I understand you correctly we already do something like this on linux.
You can see the code here: https://github.com/tianocore/edk2-pytool-extensions/blob/master/edk2toolext/environment/extdeptypes/nuget_dependency.py#L31
For better support can we move this conversation over to the pytool project. Please open an issue here: https://github.com/tianocore/edk2-pytool-extensions/issues
Thanks
Sean
