Sorry I was getting carried away with the Star Trek theme :o). I think it can
only be done using BSR as a previous poster mentioned

ip pim bsr-candidate type number hash-mask-length [priority]
The type number part of this refers to the interface whose address is used to
identify the BSR. The hash-mask-length is how many bits of a multicast group
address to use before consulting a hash table of RP's. The priority is for
election as BSR. The hashing allows load balancing across multiple RP's for a
range of groups. Only one RP will be used for each group, but the hashing will
divide up which RP is used for which group.
