I think there should be an option to make it so the player can jump to the same region, and also regions that are higher and lower by 1.

Hi there
This is too specific, I'm sorry but will not add an option like that. Maybe if you tell me what I'm trying to do, I can help you better. There are already several options to allow/prevent, enable/disable the player from jumping, including switches, events, regions and terrain tags.
So maybe if you tell me what you are trying to do, I can help you find a solution.
No it's not.
But if you want to achieve the result of "Can Only Jump To Same/Higher/Lower Regions", just set the jump check to "Can Jump". This will be the same as your qoute. Player will be able to jump on any region, higher/same/lower.
That is why I asked what you are trying to do, because if I could know that, I may have better chance helping you, as so, you will have better chance being helped.
