Can we aggregate data across regions into a single account for an "Aggregated Data Account"?

If we deploy in a “hybrid” configuration where we use a Lytics Private Instance (single tenant environment) in Europe and Asia-Pacific, and we use Lytics multi-tenant in the United States and North America, can we still get the benefit of “one platform” with the ability to aggregate the data in these different accounts and different instances into an “Aggregated Data Account” for a single view of customer or analytics use case? Will there be any functional impact on the fully integrated Lytics capabilities across regions?
