VRA8: How to Assign Network Profiles per NIC on blueprints

I tried to create a blueprint with 2 NIC and I want my client can choose the subnet for NIC.

Can you please help me check any problems with my code?

Network1:

      - 10.72.119.x/24

Network2:

      - 10.72.107.x/24

resources:

  Cloud_vSphere_Machine_1:

    type: Cloud.vSphere.Machine

    properties:

      name: '${input.TenVM}'

      image: '${input.OS}'

      cpuCount: '${input.CPU}'

      totalMemoryMB: '${input.RAM}'

      networks:

        - name: '${resource.Cloud_vSphere_Network_1.name}'

          assignment: static

          deviceIndex: 0

          network: '${resource.Cloud_vSphere_Network_1.id}'

        - name: '${resource.Cloud_vSphere_Network_2.name}'

          assignment: static

          deviceIndex: 1

          network: '${resource.Cloud_vSphere_Network_2.id}'

  Cloud_vSphere_Network_1:

    type: Cloud.vSphere.Network

    properties:

      name: '${input.Network1}'

  #  constraints:

  #    - tag: '${input.Network1}'

  Cloud_vSphere_Network_2:

    type: Cloud.vSphere.Network

    properties:

      name: '${input.Network2}'

      constraints:

        - tag: '${input.Network2}'

Thanks
