vRA Reservation Policies / Network Profiles

Is there any way that you can manually exclude certain server names from vRA.  For example we may have a server named SERVER200 which has already been manually deployed via vCenter.  If we are deploying a new VM using vRA then we want to ensure that it won't deploy a VM with a similar name i.e. SERVER200A  (note the suffix 'A').  This is just simply to stop our users getting confused with 2 VMs with a similar name.

Thanks!
