Huge number of Inventory Orgs and need to confirm ideal number of Cost Orgs Grouping

Summary:

We have 900 Inventory Organizations, and Oracle Support has informed us that it is not possible to use a single cost organization and cost book for all of them. Therefore, we need guidance on the ideal way to group our Inventory Organizations to establish appropriate cost organizations. Additionally, we would appreciate examples from existing clients or estimated configurations, such as grouping 100 Inventory Organizations under one cost organization and cost book.
