Setting underground belt direction in blueprint

Is there a way to set a direction of underground belt while placing ghost image, for construction bots?

When i place ghost images and rotate the item, it simple changes its input face and not the belt movement direction (in or out)...

For blueprints, just make sure that you manually place the underground belts in the correct direction first and it should work.
(It worked for me at least on vanilla builds.)
If it does not work, you can try placing a normal belt that follows the direction of the underground belts alongside with the blueprint.

For ghost building, what I did was I always to make sure that the input belt gets build first before placing the output belt.
Because the first underground belt that always gets placed first by the bots will always be the input belt. (And the same applies to player when they place their belts.)
