I am creating a Maunal Elevation level symbol (using the genetric annotation family. I have succussfully created it to be an instance, I have the line being able to move by typing in a distance. But what I would like to do is instance of having to always type in a distance to make the level line longer or shorter is to have the graphical blue triangle to allow me to move the line as I see fit, similair to a variable function. Can someone tell me how to get that feature on?
