you can send it in the clanchat and a other member who has got the same th lv can import it.
so you can share your layouts without it taking so much time to copy
That's fine if they add it, but you will get more benefit coaching them into how to do good layouts themselves ("teach a man to fish" per se') He is going to need to maintain that layout going forward adjusting it as things are added and upgraded so he needs to know how to do this not just depend on others to hand it to him.
