Ability to draw on the board.

The concept here is the ability to take a pencil or pen and be able to draw on the board. Specifically used for assisting in team collaboration, pointing at a specific text box, group, annotation, whatever that might be on the board. Thank you.

I'm attaching a video so it's easier to see and understand.
