editing a completed range session?

hello, i just used my r10 for the first time and hit around 25 balls.  i saved my range session and after the fact i wanted to go back and edit my club choice per shot, is this possible?

when i view the session it has an edit button and when i select the shots i wish to edit there does not appear to be anything i can actually edit.

i am using garmin golf for andriod.
