RDS 2012 R2 - VDI Naming

Hi there,

I need to implement four VDI Pools:

2 Personal Managed Pools, Windows 7.1 SP1 & Windows 8.1 -
2 Pooled Managed Pools, Windows 7.1 SP1 & Windows 8.1

Following Naming is a customer requirement:

"V" as Prefix and 5 Numbers as Suffix.

Pool1: V10000, Pool2: V20000, Pool3: V30000 and Pool4: V40000

This should allow me to have a continuous numbering within the Pools for ex. till V29999.
Also I need to use the Prefix for all four Pools - "V".

But how do I have to set the Prefix and Suffix right. Is there a variable I can set. I tried both, GUI and Powershell.
It allows me to use the Prefix "V" only once for all the Pools.

Thanks for advise.
Cheers, Al
