Smart automation point levels

A very common action I do when placing a master-wide automation (basically to fade out the end of the song) is I have to go to the start of the automation and copy its value, which is always 80, and then create the point near the end and paste the 80 value. I'm thinking I do this too often for it to be so "hard" to do. Maybe smartly detect that I might want to copy 80 on the new point and provide some item in the context menu to pick it? It's not a big problem like it is, but maybe could get better.
