Hi,
Thanks for posing in newsgroup.
From your description, you want to add intra-site to the IE trusted zones.
If there is any misunderstand, please feel free and let me know.
To achieve this goal, we recommend to use Group Policy setting.
Group Policy Object--->User Configuration--->Windows Settings--->Internet
Explorer Maintenance--->Security--->security zone and content rating
If there is a standalone workstation in workgroup, Local Computer Policy
also can be configured for adding trust site in Internet Explorer.
