REST API to copy dataset from one workspace to another and attach new dataset to different dataflow having the same schema

Our Datasets require significant space, therefore we replicate a new workspace for each client. In all of our workspaces, all entity schemas are identical. Current REST API's get us part of the way there. Reports are easy to clone and assign to new dataset. When a master dataset is modified, we need the ability to replicate that dataset from a master workspace library to the client workspace and attach it to the local workspace dataflow. We would then refresh the new dataset once it is in place. Currently the cloning the dataset creates a shared dataset which references the original dataset (and dataflow). A REST API to perform this process would allow us to automate our maintenance.
