Excluding admins from Administrative Template

Hello

On my Windows Server 2008 R2 Enterprise machine, I have set the GPO in the User configuration->Administrative Templates->Windows Component->Remote Desktop Services->Remote Desktop Session Host->Session Time Limit to force any remote desktop connection to disconnect after a certain inactivity period.

I need my administrators to be excluded from this GPO. Is this possible?

If not, how can I get the same result but excluding Administrators?

Thanks!
