You can do this by contacting both Green Dot's and Netspend customer account service department. However, you should note that Green Dot and Netspend are both non-traditional financial vehicles. This means that they are not affiliated with financial institutions like regular bank accounts. In order to perform transactions such as money transfers, you need a more involved approach.
