Create VM from template - vhd file automatic rename ? scvmm 2012

Hi,

i know that SCVMM 2012 can modify the VHD Name during the deploying of the VM from the Template only when i choose Place the virtual maschine on a host. But when i choose Deploy the virtual maschine to a private cloud. Theres now way to chance the VM Disk Name. Can i work with variables or something to change the VM Disk name automatic to the VM Name? for Example %hostname%_disk_1.vhd ?
