Copy Parent entity data from one scenario to another scenario in FCCS with out running consolidation

Hi Team

We have a requirement in Oracle FCCS to copy data, including JVs, from one scenario to another for all entities (parent and child) from historical years through the current year.
The Copy Data functionality works for base/child entities, but parent entity data requires consolidation. The challenge is that consolidation rules have changed frequently over the years, so the current rules may not reproduce historical results correctly.

We have Only configure consolidation rule ( standard rule from Oracle and Custom rules for elimination )

How to copy Parent level data (which include Calculated and Elimination data). We don't want to run consolidation.
