Storage reconfiguration is not limited to elements. You should be able to configure amounts and ranges of storage, but the amount or range must be a multiple of the increment size. Unfortunately, there is no MVS operator command to display the increment size. However, if you use SYS1.MACLIB(IHASCCB) to map the area pointed to by CVTSCPIN (CVT+340), then SCCBSAI (or if it is zero, use SCCBSAIX) allows you to compute the increment size.
