When using the new price list feature and adding several prices for an item on the price list lines, the prices for this item can be shown directly from the item card when clicking on "sales prices".

Editing of the existing prices is possibly, but it is not possible to add a new price for the active item. Therefore the user has to open the price list (with e.g. more than 10.000 price list lines) and adding a new line which is very difficult.

I would suggest the possibility to add a new price list line directly from the item card.
