Moving multiple selected sound gadgets into a slice mapper should work as expected

Whenever you move selected objects into some other object in Dreams, all the selected objects are moved. Apart from when moving a sound gadget into the slice mapper. (Which for those that don't know, deleted the moved gadget and puts all its slices into that slice mapper.)

Currently, only the gadget under the imp is moved into the slice mapper. As seen here. So this is unexpected, because of the inconsistency.

I'd suggest all the selected sound gadgets should move into the slice mapper this way. (As long as they can fit. Maybe it goes hovered, then creation order, until it can't fit them all in and then doesn't move that last sound gadget.)
