Do we have to sacrifice a baby ewe for this to happen!? >.<;

It's rather annoying to transfer all the members from the old LS to the new and occasionally tend to have some of those members, who will not be back from vacations,finals, ect., coming back confused without a LS. It's really time consuming and not fun at all! Please SE give us that tool and please don't let us wait 6+ more months after the battle system changes to implement this.
