I'm probably not using Price Level the right way. Let's say a full week of meal plan is $50. When entering orders for each week, I hope to have a drop down to select the number of days in a week, as it might change due to holiday, where first day/ last day of school lands in a week. So when I select the number of days, it will look like 2nd screenshot.

But I also would like the base price to be flexible, let's say if the customer has a special pricing of $35/week instead of $50, i am hoping the 1 day will change to $7, 2 days will change to $14 etc.
