I used to have this option, weekend pricing, but ABB took it away when I tried smart pricing. It was under pricing, set base rate, then used to have an option for weekend pricing. I think its to make smart pricing more attractive.
You would need to select each weekend to change the price manually if you don't see the weekend pricing option. You can select multiple dates, by using shift click (they don't even let you use CMD click), the usual keyboard shortcut then change selected dates rates. You can also custom set rates for specific nights in smart pricing as well.
Another tip, I keep my smart pricing range within $5 from highest to lowest. Each place is different. If I had a second rental unit I might take a completely different approach.
