Looping through buttons

[clear garden]

Hi. I couldn't find anything online about it and don't even know what to search for.
I want to be able to press up on my top button and select the lowest one. And the other way around. When the lowest button in my menu is selected I want to press down and select the top button.
I don't know how this is called. Looping? Endless scrolling? Stepping through?
Anyways... I'm using InControl and on the EventSystem I just have their Input Module. Any ideas?

use manual navigation on the top and bottom buttons

and assign them to each other for up/down navigation as necessary
