Multiple draggable components?

I’m attempting to make a prototype that contains a list on the left side of my window. Each of the list items needs to be draggable, to be dropped into a graphic on the right side of the frame.

I have this prototype working for the first item in the list, using an oversized frame with both horizontal and vertical scrolling enabled. However when I attempt to add the same interactivity to the second or subsequent items via their own frames, the interactivity doesn’t work.

I tried making a rectangular ‘hole’ in the frame of the first item, so as to not block the second item from being draggable (since it is on a layer beneath), but this did not work.

Are there any workarounds for this?
