Modify amount in Sub Ledger Accounting

Hi

In a scenario where for secondary Ledger Accounting requirement is different from Primary Ledger;

Where a transaction require adding accounting lines and dividing amount; for example If base sla transaction is

Expense Dr          100

Liability Cr                    100

Secondary Ledger accounting require

Expense Dr            80

Another Ac Dr        20

Liability Cr                    100

.

Can we calculate amount also in SLA ?

thanks
