yes, since I may want to create virtual machines from this template 
where the 2nd disk is sometimes on SD1 and sometime on SD2 (just like 
today, where i can instantiate a VM from the template on multiple 
storage domains)
The new feature will just allow me to not clone all the disks of the 
template to all storage domains, rather a subset.
