Can you add an entire Top Level Domain to a Security Zone using Group Policy?

We use an Administrative Templates Policy located here:

Computer/User Configuration\Administrative Tools\Windows Components\Internet Explorer\Internet Control Panel\Security Page\Site to zone assignment list

To control which websites are in the Trusted Sites and Intranet Zone. We have many specific subdomains of top level domains like .gov and .mil in our trusted sites, such as

http://*.fbi.gov/

and

http://*.army.mil/

These work fine. We are wondering if we can add entire top level domains to trusted sites, so is it possible to add

http://*.gov/

and

http://*.mil/

so that any subdomain of .gov or .mil was a trusted site?

We are using this policy to control the security zones on IE7 and IE9.
