Hello @LeaningTower,
Thank you for reaching out to the Community. Based on your description, it sounds like you have Automatic Entry turned off and your investment transactions are downloading into the section below the register. Currently, the default sort order is the only option until you accept the transaction into your register.
You are not the only one who would like to have the ability to sort investment transactions before accepting them added to Quicken. I would recommend viewing this Idea post and adding your vote and a comment. Ideas that get enough votes may be implemented in a future release.
Thank you.
