Suggestion - Faster Viewport Resolutuion Changing

When I use overlays or things like that, adjusting the custom x, y, width, and height is time consuming. I tried the r triggers and joystick and such, even tried to find a way to type them, but no avail. It takes a little over a second to move it 10 pixels and I change it quite a bit. When I forst booted up, I was changing it to 1920x1080 and it took a while to do. Is there something I’m missing, or is left and right the only way to adjust it?

It’s probably faster to do it in the cfg via text editor if you know what rough size you need and then you can trial and error the last bit.
