[ovirt-users] Can ISO Domain be shared across multiple data centers? Ovirt 3.5, 3.6? Does not appear so

Hello All, Tried setting up NFS ISO domain which works on one host/local datacenter. I do not want to have to have multiple copies of iso files on all hosts. If I try to import pre-existing ISO domain, I either get an error that storage path exists or the dialog just does nothing. Does not appear possible. Any tricks or workarounds?
