WDS computer names, starting from 15021

Hello,

I'm working on a tablet project. We are installing 330 Acer Aspire Switch 10 tablets with WDS.
Now I want to name the tablets automatically. We are numbering them like this:

ABCD15021 to ABCD15351

Is there an option to start numbering at 15021 till 15351?

I could do  "ABCD15%03#" that would make it number from ABCD15000 if I'm right.
Is there any solution for this?

Thanks for reading and your time.

With kind regards, René de Meijer. MIEGroup.
