similar to Satisfactory, when placing multiple assemblers in a row , the only way t odo 2 inputs on the entire row is to bring in one item at ground level and then the other item at a lower or higher level using Conveyor Vertical Lift with , splitters and mergers.

I am suggesting an equivalent, as Splitters can only do so much and the sprawl is unreal spagetti.

could be used for many combinations, not just assemblers or 2 in 1 out machines, .
