I found this thread from three years ago
https://community.quicken.com/discussion/7912812/investment-register-transaction-sort-order?utm_source=community-search&utm_medium=organic-search&utm_term=register+sort+order
And it STILL doesn't seem like Quicken has done this right (I'm using R64.35). In that thread, there is a Preferences screen with the option "Sort same-day transactions by security name". Even though I have that checked, that is NOT what happens. It Sorts by Date, then by ACTION, and THEN by security name. For each date, all the Boughts are first, sorted by security name; all the DIVs are next, sorted by security name; and all the Solds are next, sorted by security name.
I want the option "Sort same-day transactions by security name" do to exactly what it says!
Since Quicken is a database, for the life of me I don't understand why there is no Sort Options to choose Column Sort Order across all the register fields. That's seems like such a straightforward functionality.
