WDS unattended.xml computer name

I have over 200 computers.

I prepared an customized unattend.xml and 200 unattend.xml. All they are same except <ComputerName></ComputerName> This setting is same with name in WDS and Active Directory computername

My question is is it possiple to have a 1 unattend.xml and this and computername setting is taken from wdscomputername?

thanks in advance
