Attribute flow precedence for Azure AD
Investments into the synchronization part (SaaS and AADConnect) are continuing, moving forward we need to able to set precedence for attributes.
Example: Attribute is imported from SaaS HR App (e.g. Workday) to a FEDERATED user directly to AAD, this attribute is also synced via AADConnect, we need to be able to configure who "wins".
This option is also very important when sync from AAD to ADDS is advancing (https://feedback.azure.com/forums/169401-azure-active-directory/suggestions/6455327-sync-azure-active-directory-down-to-on-premises-ad)
