Offering % discuont

Hello, I'm new to Airbnb and was wondering if you can add a special % discount for certain days. I know you can by the week or month, but I just want to add "15% off for this weekend only" discount to get people in the last minute when things aren't booked. Is there any way to do this without having to just adjust the price. I would like it to show a % discount than advertised a lower price. I know that the first guest got 15% discount so just wondering if there is a way to do it again for certain days.

thanks
