Friends can share charts and draw on them

Is it possible to make it so more than yourself can watch the chart and draw on them? I mean if you and your friends can watch the same charts and draw on them live, that way its easier to show them what you mean and we can learn from eachothers experiences. Example: I pick a chart and send the link or whatever to my friend. He opens the link and see the same chart as me. When i start drawing, he see everything that i do and can ask questions or/and come with inputs.
