Defining a storage group as OVERFLOW provides most of that function by default. I believe the difference is that QUINEW volumes are used as a "last resort" whereas OVERFLOW volumes are used when the high threshold will be exceeded.
>From "defining storage group attributes" in the Knowledge Center: If all volumes in a non-overflow storage group are so full that the current allocation request will push them over high threshold, while volumes in the overflow storage group are not so full, then the new data set will be allocated on a volume in the overflow storage group. The assumption is that all other attributes of the non-overflow storage group and overflow storage group and the volumes in those storage groups are the same.... Volumes residing in overflow storage groups are preferred over quiesced volumes and storage groups. If you quiesce an overflow storage group or volume then the quiesced volumes are preferred over quiesced overflow volumes. Regards, Greg Shirey Ben E.

Hope this helps.
