When I buy a bond, treasury, or CD at Schwab, Quicken correctly assigns the Investments:Buy Bonds to the transaction. But when the security matures, the way Schwab reports the transaction does not cause Quicken to properly record the result in the Investments category (Investments: Sell Bonds).
This is a real problem.
To solve this I would like to have manual access to the Investments categories. You could make this an opt-in feature with a warning of some kind.
