Maybe??? Not super excited.
Need to know if this is a pattern or not... Push button to go somewhere and get a file to attach, as with MMS. Or reference a person, as with address to send to. Still a field, usually, and you activate differently to cross-link, etc. Significant variation due to calling services on mobile; you can "attach" the camera, which opens the camera, then when done you select that photo and IT is attached. Maybe too far, and we drop this whole line item.
