We are trying to add all "sites" to a preservation policy in Office 365 Retention.  I found this (https://technet.microsoft.com/library/dn767952(v=exchg.150).aspx) regarding how to accomplish it for the mailboxes, and would like to apply the same logic to the site retention if possible.

Adding All Sites to Office 365 Retention Preservation Policy

Office 365 is a group of software plus services subscriptions that provides productivity software and related services to its subscribers. Office 365 allows the use of Microsoft Office apps on Windows and OS X, provides storage space on Microsoft's cloud storage service OneDrive, and grants 60 Skype minutes per month. Office 365 includes e-mail and social networking services through hosted versions of Exchange Server, Skype for Business Server, SharePoint and Office Online, integration with Yammer, as well as access to the Office software. All of Office 365's components can be managed and configured through an online portal; users can be added manually, imported from a CSV file, or Office 365 can be set up for single sign-on with a local Active Directory using Active Directory Federation Services.
