Displaying the last event with tracker capture

Hi all,

I set up a monitoring system with the tracker capture an 8-step
process to evolve in which villages. How to capture only the last
event for each organizational unit. I want from this information to
establish a scoreboard either pivot table or event report.

Eg: if an OU crosses the step 1, step 2, step 3 that the system
displays only the step 3

Also, how to remove an OU already enrolled in the tracker capture?

All ideas are welcome

Regards !
