Control OneDrive Sync App with GPO to sync known folders, but exclude the Pictures folders.

Hello, 

I have been tasked with rolling out OneDrive for Business to the entire organization. I have so far figured out the basics of rolling out the OneDrive app with Group Policy, and how to configure "Silently move Windows known folders to OneDrive." I have, however, been unable to figure out how to exclude the Pictures folders from the sync, via GPO, with the Silent Move enabled. 

Is there a way to do this via GPO with OneDrive? 

Thank you very much in advance!
