Drag-building underground belts in reversed direction

[Amegatron]

TL;DR

Possibility to drag-build underground belts in the reverse direction of the drag.

What?

Currently, if I'm drag-building underground belts, their direction will always correspond to the direction of the drag: for example, when running from right-to-left and placing underground belts, they will only be placed in the same direction - right-to-left.

Instead, what I suggest, is to have a possibility to place them in the reverse direction. So that in that same scenario, I could be running from right-to-left, but placed belts would be directed from left-to-right.
This could be done in such way:
1) I place a first underground belt in the direction I need (for example, an "intake" belt from left-to-right)
2) Without releasing the mouse-key, I start dragging it to the right, and belts should preserve the direction of the first underground belt in this drag.

Similar to placing usual belts, actually, which respects the original rotation of the belt in hand rather than forcing the direction of the drag.

Why?

It is a very common scenario when you first build some production, and only then drag input-belts to it. So, you're running away from this production, but the belts should lead to this production. Currently it is very inconvenient to place such underground belts manually. You either first put them, and then switch them to the opposite direction on you way back (chances to miss some section are high). Or you fist place the ghosts by copy-pasting other betl-lines, and then manually place each individual underground belt.
