About subway view editing

Suggestions on how to add a new event to a Subway view or import an event from a different view. 1. Allow dragging selection. 2. Specify where to put it down when dragging and importing an event from another view. 3. When creating a new event as a shortcut after editing the event, create it at the next location.

I’m creating a basic frame in the Subway view, and it’s a headache whenever I create a new event or bring it from another view. I think it would be desirable to do it as above, but will the process be difficult? I’d like to ask for it.
