Creating Windows 10 Custom Libraries and Linking Sharepoint Document Libraries

We have a client that is looking to have their user’s private (not personal) Onedrive folder appear along with a document library from Sharepoint under one folder. It seems easy enough to manually create a custom library and pop it into a GPO, however, since the private folder will be different for each user, i’m looking for a way to script the process of adding the private folder as well as the document library under the new custom library. I can’t seem to find what i’m looking for using Google/Bing. I’m also fully aware i may not be looking in the right places.

Can anyone point me in the right direction?

 

Thank you in advance
