How to allocate the Budget balances from one segment to multiple segments

Requirement: We want to allocate the Budget balances from one Fund to different funds based on some Cost Center percentages. We are able to achieve GL balances using Calculation Manager, but we are not able to use the same functionality for Budget balances.

Please suggest if we have any solution for this.

As a workaround, we are using the Budget transfers using spreadsheet, but it's a cumbersome exercise for the business on a regular basis.

Thanks,

Mahesh
