Moodboard > Line, Arrow & Shape Drawing Tools

I would love to be able to add lines or shapes to a moodboard. I recently created a simple wall paneling example to show a client. Due to the space and size of the space I decided just to draw it up rather than use a 3d approach. I had to design this in Microsoft powerpoint then save as a jpeg and import then add to my moodboard. Something small, but could be useful to have this included.
