As always, maybe this is already in Canny, but I can't find... Or is it possible but I'm just not seeing the option somehow?

It seems we can create a NEW task from an image or link, but we can't ADD anything to an existing task. Pretty annoying if you have a project task and you run across a piece of information that you want to add to the task to remember for later. Currently we have to create a new task then merge it later. Then we have create a reminder for ourselves so we remember to merge LoL!
