Structural Analysis Package

I am trying to add a label "100 lb/in" on both of the load distributions. Every time I attempted it, the labels pop up in places I did not intend them to be. I want them to be on top for the horizontal beam and to the right for the vertical beam. Furthermore, I am trying to add "A" at the bottom of the horizontal beam and "B" to the vertical one to the left. How can I accomplish this. Thank you
