For the Q&a Section, How to Reduce the Time?

Not like it really matters, but I wanted to reduce my question from two weeks to a few days. Silly me, thinking it would cycle back to the beginning when I click on "extend expiration" because I didn't see a "reduce" or "change expiration." I really don't want anyone to go to any trouble, but if there was a quick fix or some button I didn't see, please let me know.
