Hi Guillaume, this thread might provide some info for you. The basic idea is that ultimately L&L templates are just posts, so any tool that allows you to manage syncing a custom post type between subsites should also work for L&L posts. There’s a native solution in the works, but since it’s a pretty sizeable project, it might be quite a while until that’s released. Maybe Distributor could work for you? I’m not sure how well it works with custom post types though. I’m sure there are other plugins for this too.
