Default Datastore

Hello folks,

Im kind of new to OpenNebula, maybe you can help out here.

I have an existing cluster, the default datastore is nearing full, I have added another and it is working great.
My question is:

I would like the images to default to the new datastore, currently I have to create a image > clone it > choose the new datastore and then its right.

Can I make the new datastore the default? So the images go to the new one automatically?

Thanks in advance,
