Adding arrow callouts with text along a path

I am finally getting comfortable with dynamo, and was asked this question by a colleague. Is there a way to create an annotation using dynamo by picking points along multiple walls and then typing text, and it adds in a path with arrows on the end of the path. My answer was simply a blanc stare. So I walked away and thought I would ask the professionals lol.
