Approve several bank proposals at once

Firm owners, firm admins, accountants and bookkeepers may do this; other roles are refused. Nothing needs switching on. It is also refused for a client whose chart of accounts is not SKR03, because payments cannot be booked there yet.
Open Finances, the tab Bank lines, and choose Review proposals. A line with a suggested match shows the suggestion and a checkbox. A line whose best suggestion is a returned direct debit or the refund of an overpayment has no checkbox: confirm it alone with Match.
Tick the lines you trust, or tick Select every proposal to take every line with a checkbox that the current view and filters show. Lines you have not loaded yet with Load more lines are not included.
Click Approve N selected proposals and confirm with Yes, approve. For each line this does what Match does with its best suggestion: it books the payment, and a rest that the suggestion explains as cash discount is booked as cash discount. At most 200 lines go in one click.
Afterwards the page says how many were confirmed and how many were skipped. A skipped line stays open and the page does not name the reason: the line has no suggestion any more, its best suggestion is not an invoice or receipt, it no longer exists, or it was refused. Open it and use Match or Assign manually.
A separate button, Confirm N rule proposals, appears when shown lines carry a suggestion that comes from a learned bank rule. It asks first and says that each one books a payment.
Nothing is approved by the import or by itself: every approval is your click. To undo a wrong one, reverse the assignment on its line.
