My understanding is you are looking for a support similar to the one provided by HOT template,

https://github.com/openstack/heat-templates/blob/96a0b0b3d2af2dbb266d1048360ab6992dc3ca3e/hot/vm_with_cinder.yaml

.. but using TOSCA template and Tacker.

We don't this support yet. However we can extend Tacker's TOSCA to support this. In fact, in the OASIS TOSCA group, there is a proposal to model "VirtualStorage" for a VDU. I'll register a blueprint for this to see if some one can help to implement this.

Tacker supports creating multiple volumes but only attaches one volume. is this the one you are looking for?
