Need ability to insert a Line Shape that reaches edge of screen

You can already insert shapes into the report. For example a line, but it is not possible to make the line stretch the entire length of the screen. For some reason there is a small buffer of white space on the left and right side of the line. This is a extremely simple request. Just need to be able to make a line that goes 100% of the way across the screen. Right now line shapes can only cover maybe 98% Wish I could submit a picture to show the issue but this should be clear enough description.
