Default [Q] lock screen screen without power button

am looking for an app to go directly to the swipe lock screen without power off so I can switch users without cycling the power button on my tablet. The power button is offset toward the back and annoying to use as well.
Also, do not want to use a proximity sensor app because it drains battery and uses hardware unnecessarily.
If this is something that is already built into android and I haven't found a shortcut, I apologize in advance.
