Add a prefix when creating an attachment that is reflective of the user who created the attachment. Specifically I would like to add a prefix to the attachment name that reflects the user who took the photo in the field. Right now for some features there are two Photo 1.jpgs for the same feature. Is there a way to add a prefix so that you have 01_Photo 1.jpg and 02_Photo1.jpg. 01 and 02 being the user in the field.
