ContextOne of the sites I subscribe to is Excel Ribbon Tips (excelribbon.tips.net), authored by Alan Wyatt. The information is useful for Excel users and VBA/Excel programmers. He also provides tips in Word...I'm just not in that mode right now.
In most of his weekly tip sheets there is a call for help from a reader, someone who has a problem they are trying to solve. The following is the one of the answers I provided.
An alternative would be to make certain the part number had only allowable characters, meaning it could now be more specific.
For other ideas you will need to visit Allen's site.
