The workflow for finding and matching missing recurring items (of which I have many, a lot of which I can't understand why they aren't matching automatically) is clunky from the Recurring screen - you have to click back to Transactions, find the missing item, open it and find the relevant Recurring item (if it lets you) for each one. It would be much more efficient to start from the Recurring tab and do a quick search to grab and link the correct transaction.
