Change Administrator password in Windows using ResourceGroup

Hello,

I am evaluating PasswordManager Pro. I installed 2 PMP agent in 2 Windows server and want to use Resource Group to change local administrator password regularly.

I tried to use Password Reset function in Resource Group. However, this function will try to change every password in Resource.

So, If I want to achieve above objective, Does it mean that I need to create following resources ?

ServerA Administrator [in Server Group]
ServerB Administrator [in Server Group]

ServerA Others [Contain other username/password etc that require no password regular change]

ServerB Others [Contain other username/password etc that require no password regular change]

Please give me some hints.
