Hello, I'm not an expert but I don't think you can do what you want. The way to separate data for applications on the same cluster is to use different tables for different applications or use multiple keyspaces, a keyspace per application. The replication factor you specify for each keyspace specifies how many copies of the data are stored in each datacenter.
You can't specify that data for a particular application is stored on a specific node, unless that node is in its own cluster. I think of a cassandra cluster as a shared resource where all the applications have access to all the nodes in the cluster.
