Hi
For your financial reporting, create an additional FSV for your non leading ledgers. Now club both the main GL Accounts and a ledger specific GL Account together under one node. For eg, you have a GL Account as Vendor reconcilliation account and another GL created for AP Adjusments under non leading ledger. Now both these GL Accounts can be clubbed together under, Accounts payable node under current liabilities. Now the business can see the total balances for AP. You have to use the FSV you would be creating for your reporting under non leading ledger,
This is how I have seen for most of my global customers and your business should not have a problem with this.
