changing part numbers in toolbox

i am having an issue when using items from the toolbox. myissue is that the part numbers given to stuff like nuts and boltsin the toolbox do not match the part numbers we use. how can ichange the part number and description of say a 1/4-20 x 1.000 hexhead bolt so that when used in a BOM it will match what our numbersare....without having to manually change and break the link in theBOM.
