Issue with loading entity currency data to multiple currency for FCC to Planning integration

While loading data from FCC to Planning, we are receiving data from FCC for Entity Currency, but we want to load data into Planning by currency.

We have a potential solution to perform multi-dimensional mapping based on the entity to the corresponding currency. However, this would require significant maintenance on the client side since there are multiple integrations from FCC to other EPM applications (EPBCS, EPCM, ENT RPTG).

Please let me know if there are any other possible approaches to achieve this.
