Using "aspnet_regiis.exe -ga" on the basis of SID instead of "user name"

aspnet_regiis.exe -ga "Network service"
The above command grants "Network service" access to the IIS metabase and other directoriesused by ASP.NET.
Is there any way to do using "Security Identifieir" http://en.wikipedia.org/wiki/Security_Identifier instead of user name, actually it is useful in Localized OS.


Thanks,
