No, not a specific parameter for multivolume, this is part of the Dataclass. Possibly your SMS management has defined a Dataclass that you can request and gives you a multivolume dataset. Besides that, you can always overrule the values supplied by the ACS routines, e.g. specify UNIT=(DISK,40). However, starting from z/OS 1.10 (or maybe 1.9), SMS has parameters that allow him to ignore your overrulings.
