Following recent reauthorization, all downloaded transactions from a Merrill Lynch IRA account show only cash amount and no share amount or transaction category flags. Quicken supplies the deposit/withdrawal designations by default. So, for example, a dividend or capital distribution will download as a withdrawal followed by two deposits of the same dollar amount with no action flags or share amount involved.
The only interim solution I see is to keep the account register updated manually after each download. This is a gross loss of functionality that should be quickly attended to.
