Figma Question

Hi, I'm new to Figma. One thing that has been bothering me is that it seems there's no built-in way to slot in components inside other components. For example, I'm building this search bar + search suggestions component. With the way I have it set up right now, I can have one search suggestion inside the search suggestions container, but if I want to add more, I have to add it inside the master component, or detach the component instance. Another thing I wanted to do was build a page layout component to keep a consistent 20px left/right padding on all my pages. But again, I can't insert content inside instances of the layout component. I don't know, is it a bad idea to try to add padding this way in the first place?
