"Item is LOST; do you wish to continue" prompt -- changing the default setting

In the Aleph circulation module, when an item has a status of LOST and it is returned on Aleph, a window box comes with a "yes/no" request before continuing the transaction. The default setting in the GUI for this choice is "no", but choosing this causes the item not to be returned. Is there a way to change the default in that pop-up box?
