Best way to have multiple account hierarchies - different for each Region

Summary

We are going live across the globe with Cloud Financials which means each country needs its own Statutory Account Hierarchy (25 different ones)

Since we want each country to be able to use their respective Statutory account hierarchy in Essbase and FR. Is the best way really to just have the 25 different tree codes/tree versions (see attached) which a user will be able to see in member selection? Or are there other ways to somehow group these statutory trees together or control the access to these trees based off Ledger Group access? Just seems strange the best way is to have 25 hierarchies out there that would be confusing for end users having to see that many.
