Gain and Loss of Sale of Asset

We want to enter an asset but when we sale the asset, we do not want Gain and losses to to go to the default account.  Is there a way to specify the gain and loss at the time of retirement?

Example, we add a vehicle to assets with the intent to resale (using Assets to keep track).  The asset will not depreciate hince NBV will be cost when asset is retired..  If we get proceeds in excess of cost, we want to record the gain to a P/L account.  Same for loss.  Currently Gains and Loss are showing below IBD and we want them above.
