JMeter - Critical Section Controller accessed by 10 threads at same time

I have single Thread Group A with 100 users that run the following logic:

*REQUEST1 
*REQUEST2
*CRITICAL_SECTION_CONTROLLER 
   -REQUEST3
*TIMER TO WAIT ALL THREADS FINISH
*REQUEST4

I would like to run the REQUEST3 by groups, only for 10 users at same time. (now only one user can at time by the section controller)

Is it possible?
