A status of "Lost/Closed" needs to be added to the Invoice status chocies. We have many occasions where we know an estimate was not approved by client and awarded to another company. having these stay as "Estimate" with no way of closing them out creates confusion. 

Having an addtional appropriate status for them to be marked in system so they are not revisited over and over would help. having the ability to move them out of the Invoice list to another location would be even more helpful.
