Rearrange Fusion Display

Hi Guys,
I have an ultrawide monitor at work and would like to rearrange my windows to have my nodes on the left and 2 image viewer on the right (one above the other). I know I can do this with floating windows, but they don't lock into position and when I restart, they main windows fully expands and I have to resize it. Not ideal. I would like to dock the 2 image viewer all within the main app windows if possible. Is there a way to do this? Thanks.
