Hide "0 available" parcels when selecting parcels in a sell transaction

This is super super annoying, especially if you continously buy shares in a company. When you select the parcel for the sell, the list will contain parcels where there are 0 shares available - this means you have effectively your whole buy history in a company in this drop down for no reason what so ever. If there are no shares available in the parcel, then it shouldn't be in the list. For me, this list is almost 200+ items long with 50% of them being "0 available" because I sell/buy continously.
