Liquidation of all items equal to and below selected item

Hi,
One of the more common things to do when you reach level 50 is to liquidate items. For me that means liquidating all items that are not pink.

As it is now i have to select each item and click two buttons to sell each item.

A button for liquidating all items equal to the selected item and below would be a great thing. With this button you could in two clicks liquidate all the useless items (ie. non-pink usually).

Is/has this been considered ?
