Hi there. You are right, this date is not easily viewable in analytics. This is a requirement that might have been documented already in the work with the new line list app. @Scott might be able to comment on this.
For workarounds/approximations, one suggestion can be that you make a program indicator that shows the number of days between the enrollment/incident date, and the report date of each program stage. Or the number of days between each of the program stages. To do this you can follow the instructions in this thread: Number of days between dates from different program stages
Hope this helps!
