Mouse Lock keeps the mouse within a rectangular area like a monitor or split, but is there an way to do the opposite by keeping the mouse outside an area? Basically, I want to create walls along the edge of my monitors so only at the un-walled sections (aka pacman tunnels) can the mouse cursor transition to the adjacent monitor. I'm guessing that can also be accomplished if the current Mouse Lock feature allows for exceptions where the Lock disables if the mouse moves through a particular edge section.

I would naturally position and size the tunnels to physically match the position and size of the adjacent montors. For example, if I have a 40" wide monitor over a 14" wide laptop, the bottom edge of the 40" will have a 14" wide tunnel positioned exactly over the laptop screen.

This feature will also need the inter-monitor mouse position to map relatively based on the tunnel size instead of the whole monitor, so the mouse transition looks natural.

Another reason for wanting this is due to Mouse Without Borders, which is has limited options to manage the mouse-transition edges.
