This can be done by making the change on one slip and then exporting just the changed field to other slips that meet specified criteria. The export button is the icon that looks like a piece of paper with an out arrow. HOWEVER, although it sounds easy it is easy to goof and make a mess. MAKE A BACKUP before you start. If you have never done this process before, it might be worth investing a small amount with an experienced consultant such as Nancy Duhon or me. Feel free to contact me if you would like help.
