is it possible to have different segments on a balance account for a crosscurrency receipts via SLA

Summary:

While creating cross currency receipts, the balancing line on the receipt is picked from the ledger setup ‘Specify Ledger Options’ and since this is a ledger setup even if there are multiple BCs in one ledger, only one BC’s code combination can be added in this setup. We have a Mexico ledger in which we have two BCs so when creating cross currency receipts for one BC the other BC's code combination which is added in the specify ledger options setup is coming on the balancing line of the cross currency receipts of the first BC.

Since this is happening for the balance account on a cross currency receipt, in order to handle this issue, we thought of creating SLAs but there is no Balance account class in SLA so we are not able to create any SLA for this. Is there anyone who has faced a similar issue ?
