@Faiz yes. That's exactly what I was asking. Thank you.
I believe you want to change the price in a specific period. The change will be different for weekdays and weekends.
So you will have to create two separate feature price rules.
One for Weekday in which you will have to select the period and then in the specific days select the weekdays.
And one for Weekends in which you will select the period and then in the specific days select the weekends.
