When a normal belt is dragged, the underground belts are placed at the shortest distance possible while avoiding obstacles.
However, I require an option to place them at the longest distance.
It would be preferable to switch this function by pressing the alt key or similar while dragging.

I think instead of automatically putting the exit at the maximum distance, move the exit with the cursor as you drag until it reaches that maximum. So if you want to stop the belt length sooner, you just stop dragging.

I intended to refer to an underground belt that switched automatically from a (non-underground) transport belt.
If you have the transport belt on your cursor, you can't move the exit.

Yeah I got what you're saying. I'm saying that a more general solution would be for the game to detect when an obstacle is encountered and essentially temporarily switch to placing the exit of an underground so that you can place the exit wherever you want or, at most, at its maximum length.
