Good suggestion, Wes - i'll keep it in mind. An equally tedious method i was thinking of is to create a new feature class (i.e. Notes, or My Places, or similar) in my GDB, load that to Collector, then select the option available to pins to 'collect here'. from then on, i could collect using that, instead of using the pins. Lesson learned...hindsight is 20/20...and all that.
I agree: i hope someone has a more wizard solution than either of us!
