How does one add a website to the Trusted Sites for a single domain user? I am looking for a way to do it on the server (e.g. server 2008 R2). I would prefer not to do with with GPO, scripts, etc.

When performing a search, I have only found ways to do it for multiple users/ everyone on the domain. Also, this should not affect the other users. For example, the standard users can not manually add a site to the Trusted Sites.
