Can ownership hierarchy be created outside Ownership Manager?

Hi experts,

As far as we know, Ownership Manager is used to create scope-entity hierarchy and maintain Consolidation Method, Percent Consolidation, and etc.

However, if a company's organization structure is huge and complicated (e.g. over 100 subsidiaries under the holding), it would be unrealistic to manually add entities for each scope.

So we consider to add the ownership hierarchy through Excel input form.

In our testing, we can use Excel input form to submit Consolidation Method, Percent Consolidation, etc. ONLY AFTER the scope-entity hierarchy is created in Ownership Manager.

If the hierarchy has not been created in Ownership Manager, even though data like Consolidation Method can be saved through Excel input form, the desired scope-entity hierarchy cannot be reflected back in Ownership Manager.

Anyone has idea to achieve that?

Thanks,

Winson
