How does “How accounts are picked” work on the Balance Sheet Schedules page?

Each schedule is a class, and a GL account belongs to it because it was tagged in Map accounts. Duties & Taxes also includes an untagged account whose name says VAT, PAYE or CIS, or corporation tax — the same rule HMRC Dues uses — marked 'by name' so it can be tagged explicitly. The balances are each organisation's cached balance sheet at the date, the same snapshots Financial Reports reads; a P&L account never carries a balance-sheet balance, so tagging one changes nothing here.
