It's a real pain in the program I'm using. For example, one layout might include your logo, another might not. You can set up a return address with your formal name, such as Joseph P. Peters and another as Joe Peters. Once you set things up the way you want it, it only takes a couple of clicks to select what you need at the moment. Yes, if there is room enough.
Some users find it helps to make the logo smaller and use smaller font sizes.
Changing the size of the logo is easy. You just right click it with the mouse, then move the edges closer together. You change font sizes just as in any Windows program. The program I've got to print labels, always screws up a column. If I fix it so the left is okay, then the right is no good.
