Is there a way to limit the amount of rows that can be added by a user?

I have a menu where you can enter your team, but I only want to allow the user to enter up to 3 team members and after 3 are added then the Add button disappears unless they delete one of the team then the Add button can show up again. I'm using this because within the app I have a selection of who to send emails and notifications to.
