Take a look at the collections API CREATE command, especially the "createNodeSet". One variant lets you specify the nodes used to distribute the collection with limited control over what core goes where through the createNodeSet.shuffle parameter.
Alternatively you can use "EMPTY" for the createNodeSet and Solr will create the skeleton of the collection in ZK but not create any actual replicas. You can then use ADDREPLICA to place each and every node exactly where you want it with the "node" parameter of ADDREPLCIA. In both cases, the "node" is the string you see under the "live_nodes" znode.
