Thanks for the reply.
This is still a nice feature to add, cause right now it only makes sense, if you catch a single off-topic post and move it. But if the off-topic goes on and there are multiple post to move, it doesn't make sense to create discussions for each post.
It would also make some sense, if moderator could split to a new discussion from the first post off-topic starts at, and all post below (which are supposed to be referring to the off-topic) would be transferred to a newly created discussion as well.
Just thinking out loud..
