Can I Mod a Listing that doesn't sell?

I have a week listed on Redweek right now. It's three weeks until check in, which means that I need to rent or cancel within the next week to not lose the points. Can I modify my listing with Redweek, which I've already paid for, to a reservation further out? Still learning the ropes here, just trying to cover my maintenance.

Jody: Since you have a do-it-yourself posting, you can change the dates and post a different week at the same resort. The only thing that cannot be changed is the resort location. Because your posting is RedWeek verified, you will lose the verification when you change the dates. A new verification runs $14.99 for rental postings and we will need you to send us a copy of your new reservation in order to verify the new week.
