Retainer maintaining price

[Killabye]

I'd like it if when I throw stacks on the market it would maintain price and quantity meaning if I throw ten on at 15 then go back to the same item it re inputs 10 and 15 so you can stack faster.

This or simply add one extra selection box in the item sale screen where you can specify how many time the same (stack of) items(s) should be posted for the same price (and in the same amounts). So instead of like monley posting 10 times same stack with same prices it will post all ten in one go.
