Visual Studio resource editor: there can only be one string table?

I created a string table in my .rc file containing my English strings - now I need to add another string table for a different language.

If I try to do:
Add Resource... -> String Table -> New

I get the error: "there cannot be more than one instance of this type".

I know I can open up the .rc file in notepad and add language in there but how am I suppose to do this from inside Visual Studio?
