Ceph : data_pool different of rbd image

Hello, I have configured several opennenubla datastores.
These datastores are attached to different CEPH pools with the option EC_POOL_NAME

When deploying a virtual machine. The ceph image (rbd) created for this machine will be stored in the same ceph pool as the opennebula image that we used in the VM model.

If we deploy the VM in a different datastore (different ceph pool) than the one used by the VM model image.
the ceph image (rbd) for this machine will be created in the same ceph pool as the image used in the VM model.
And this ceph image will have the data_pool (EC_POOL_NAME) associated with the different datastore.

Same thing if we add a disk from a different datastore than the one used to deploy the virtual machine.
This disk will be stored in the same pool as the system image and with data_pool associated with the different datastore.

Is it possible to deploy a second disk from a different datastore where the ceph image and data_pool are both associated with different datastores?
