can we have a line that would be reactive ? ( on select, on click, etc) ?
should I create a custom object , or anything native ?

context: 
I am drawing diagrams (schema) ( imagine ump or other mind mapping ), and I have used static text to have the text cickable. how can I do the same with lines ?
or Am I doomed to just detect the click point , and manage the mapping to the object myself ?)

Happy Easter
