Inherit region from parent
When creating a new resource, the region defaults to South Central US; so requires changing on every new resource added.
Better would be for this value to default to the same region as the resource's parent; so allow a default region to be set for a subscription (https://feedback.azure.com/forums/223579-azure-portal/suggestions/6715615-when-selecting-a-location-how-to-save-as-default) and have all resource groups under that sub default to that value. Then have any resources created in the resource group default to that resource group's region. This should lower the effort of setting up a new environment with no negative side effects.
