title: Preferred locations in Cosmos DB SDK v3
body: <p>In CosmosDB SDK v2 it is possible to setup preferred locations during client creation (via <a href="https://docs.microsoft.com/en-us/dotnet/api/microsoft.azure.documents.client.connectionpolicy.preferredlocations?view=azure-dotnet" rel="nofollow noreferrer">ConnectionPolicy.PreferredLocations</a> setting). However, I don't see similar setting in Cosmos DB SDK v3. As per my understanding, the closest setting in v3 is <a href="https://docs.microsoft.com/en-us/dotnet/api/microsoft.azure.cosmos.cosmosclientoptions.applicationregion?view=azure-dotnet#Microsoft_Azure_Cosmos_CosmosClientOptions_ApplicationRegion" rel="nofollow noreferrer">CosmosClientOptions.ApplicationRegion</a>, but it allows to provide single region only.</p>
  
  <p>Is there a way to to setup list of preferred locations in SDK v3?</p>
