Enhancement request: belt merger into half-lanes

[thomasdeniau]

Hi, Would it be possible to add something that takes one belt of A and one belt of B as an input, and produces a belt with A on one lane and B on the other? (Given that just making both fall into the same belt at a 90 degree angle is unbalanced, preferring one side of the belts to the other). I had found an awesome extremely small (like 4x6) blueprint for doing this but for the life of me I can’t find it anymore. There seem to be some solutions on Reddit but all the Imgur links are dead. Thanks!
