Is there a way to only use <POA> Users in Safeguard Enterprise?

Hello, 

I have installed and configured Safeguard Enterprise and deployed to a client machine but Im aware that POA does not activate until the first user authenticates. Once this is done that user account has a key and certificate assigned and is classed as the owner? 

A requirement in our deployment is that a seperate account is used at POA and there fore I do not want to use the windows logon account for POA? 

Is there a way to tell safeguard to just use the POA users configured in the POA group Assignment in the Management Centre and NOT wait for the initial logon?

Thanks in advance

James
