Forced position for supports

It would be nice to have way, how to "force" position of supports for pipes and belts when building. When I need make supports on specific place, in this moment I must break pipe into more parts. As result there is "double support". Yes, I can remove this one piece, but it is irritating. Problem is same like in "Pipe/Conveyor Support Structure Alignment", I need to make pickups and trucks go under pipe bridges.

Very much this, it would be nice if supports were their own entity and could be placed separately, then belts connected to them.

(Pasting from my Steam thread)
Conveyor/Pipe columns driving me crazy
I'm cool with conveyors/pipes require support columns and I'm even cool with trucks not being able to drive through them.
But why is are the conveyor/pipe columns set on a different grid than the base bulding/construction grid?
It took me ages to figure out that their grid is actually the same as the mining/dumping designation grid, so now I'm putting down some fake dumping zones so I can predict easily where the next column is going to end up.
Argh!!! :)
Cool game tho. The best.
