Making Frames inside components accept children

When creating components I often feel Code has much more flexibility than what we can design in terms of components. For instance if I wanted to design a popup design, I know the style of the Title, action buttons, but I never know what the contents of that popup will be.
In many such cases I need to create the content outside the component when actually it should be inside the component.
My proposal is when the Frame is created as a component then any from inside the component should have a option to mark it to accept children. That way in the instance the marked Frame will work like a regular frame which will accept any elements we put in there. This will be helpful Header designs, Card designs, List Item designs and much more.
