Update dimensions between Planning applications (EDM, EPM...) ?

Hello All,

We have one Core Planning app and three Local Planning apps (in other three countries). Local Planning apps must have all dimension information and objects coming from Core Planning app + they can add their local members and objects if needed. Once we are doing updates in Core Planning app, we have to migrate these updates to all three Local Planning apps. In order to maintain Local Planning apps always up-to-date with all evolutions done in Core Planning app, today I'm migrating each month :

• dimension updates manually, because if I will extract dimension snapshot from Core Planning app and import it to Local Planning app, it will erase Local alias, where each country put alias in its language. The Default alias is in english and common everywhere.
