I apologize in the delay in getting to your question. This isn't directly possible in ProtoShare. That is, you can't use the native components to ProtoShare to take information in one component and read it in another. It may be possible to use some method with the HTML components such as sessions, but I don't have an example of that.
What you can do is using states simulate a user selecting a value from a component, with a fixed number of pre-selected values, such as a selection box, and then use that state elsewhere to display specific components.
