It would be useful if geotagged attachments (photos) collected as part of a polyline collection session in Collector would be placed at their proper geolocation when that polyline is displayed. Think of a feature collection workflow within a polyline collection workflow.
I'f I'm running a polyline collection session - say driving a road segment looking for damaged signs, if I want to take photos of damaged signs I must end and sync the polyline collection session, open a feature collection session, take the picture, the re-start the polyline collection. It works, but it's cumbersome. The ability to have the geotagged attachments displayed at their proper location would be very helpful.
