As a Figma user, i would like to have the ability to add “items” to components.
For example, to add a new selection option in an overlaying menu component or adding a new row to a table component.
Currently to achieve this ability i have to create sets of components with either many items already existing, or several ranges of items (5,10,15,20 items) this creates more components to manage and is not scalable. if i need to add more, i have to detach the component 
Here is an example of how i currently work:
An awesome ability would be to also rearrange the items within the component (without breaking it!)
I would love to see this feature and hope you will consider it.
Thank you!
