Started Crossfit recently. How can I still maximize hypertrophy?

I used to go to my local gym 4-5 times a week, for a couple of years, but when they pushed their prices up too much, I decided to try CrossFit for a year and see how it is.

The workouts are obviously a lot of fun since it is still novel and new to me, but I still want to get as much hypertrophy and muscle gain out of it as possible.

What would you recommend I do to achieve this? Should I add a few isolation exercises at the end? Or go slow on the eccentric even though it will make me perform worse in the WODs?
