'93 sedan door locks

I have both a '92 and a '93 Lumina Euro 3.4. The '93 has the annoying and hateful feature where the doors automatically lock when you throw it into gear, but they don't UN-lock when it goes back into Park.

Can I disable/disconnect a switch or sensor at the shifter to prevent the doors from locking?

Is this somehow "programmable" via the computer like on a Trailblazer? I haven't had this car long, and there was no owner's manual included.
