Coveyor network

[Bourbon20147]

I would like suggest to add a conveyor network. As example - you create some production. But you're conveyor line is occupied by useless trash - as example - you create the electronic circuit production line. You need the steel plates? No, your line occupied by copper cables! It's very boring - every time come to base and destroy the mistake. So, there need the conveyor network. It working by the simple way - you set needing value of some material (an equal number or something else) and you dont care about occupying the conveyor line. Extra materials - they will be taken by manipulators for another line or something else.

I know there is no real "wrong" way to play Factorio, but if your belts are full of random stuff when you try to output the products from your assembling machines, I'd say there is a flaw in your design.

I think this suggestion will turn the whole idea of Factorio's belts upside down.
See Koub's recommendation, I would move this to Game-Play-Help if nothing against it.

Why is copper on your steel belt ?
