It can certainly be done by adding additional columns in the UUT_RESULT table and creating your own schema but you might be better off creating a report (I'm assuming you're using Access) to present the data. What you want to do is frowned upon in database design because the data is not normalized. The original schemas in TestStand were like this with a UUT_RESULT table and a STEP_RESULT table. It was not normalized because there were columns always unfilled. For a pass/fail test step, the numeric limit and string limit columns were unfilled, for a numeric limit test step, the string limit and pass/fail columns were unfilled, etc. This results in inefficient writes, database size, searches, etc.
