How do I add 'collections' to my pages?

Hello,

Not sure if my title makes sense. But basically, when I design a team bio page, that displays an overview of a team (such as a picture, name and short bio). How can I set this up in Pinegrow, so that in the WordPress Customizer I could add more team members to my page when needed? Basically duplicating that ‘template Team member’ and adding new content (new image, new name, new bio) to it?

Other example would be a FAQs section. How would I set this up in PG, that from the WP customizer, I could add new FAQs?

Thanks a lot for any pointers!
