On a sale with a price list selected:
- the unit price of a line is computed automaticly when you change the quantity of the line at creation or modification;
- so when you modify the price list selected on the background,
- and add a new line on the sale after this modification,
- it’s the new formula that applied,
- and you can have two lines of a same product with two unit price computed differently.
Like on production with the “Reset to BOM” button, is it possible to have a “Reset price list” button that recompute unit prices for all lines of a sale?

The [_Modify Header Wizard_](https://docs.tryton.org/latest/modules-sale/design.html#modify-header) recompute already the price of the lines.
