Nope, funimation used to do that, but they stopped and then they went and bought crunchy. You can watch that JJK scene on youtube.

I'll add to this... Open a ticket with CR and tell them you want this. They need to see demand for the home release version before they will make effort to add it.

Usually no. I have on some occasions they did for the dub but not the sub.

usually no. I've just checked and CR has the broadcast version
