[2020] Multiple Manufacturers starting simultaneously

That is correct @Timneh. It is something that we would like to have, but due to the resources issues, this is preventing it from happening currently.  

Well, it is not the ideal solution, but it helps!

While we can't queue all the manufacturers, you can start them with a good finger patter movement from the app. You will have the option to toggle between "next" and "prior" same manufacture (any level). So you can produce-next-produce-next... etc. You will go much faster than PC, and you will start to produce 100 t1s in about 30 seconds!
