When routing data out of a for or While loop, indexing is usually selected. A Simple LEFT-Click in the actual tunnel node should select the next (Last Value) and better yet, keep selecting the next available option (Concat, Conditional) (there are only 4)
This would be a big time saver as 90% of the time when you don't want' indexing', you want 'Last Value' MUCH less cumbersome than 2 menus deep right click selections.
Same logic as older one-click True-False Slider constants.
