Customized Test Case Execution statuses need an option to turn the Defect button on or off

When creating a custom execution status, I would like the option to trigger the D button to appear, or not to appear 

The only statuses that do not trigger the D button to appear are "not executed" and "pass" 

Use case: I'm trying to create an "Approved" status, and I don't want the D button to appear. I could change the system default "pass" to "approved", but then then the custom status for "Pass" would trigger the D button.
