Language Bar specific keyboard layout selection (ADM)

Question

I am trying to get specific sub-types of keyboard layouts to deploy with GPO.  
We have the GPO .adm and it is deploying and calling the correct keyboards, but doesn't seem to be able differentiate between the sub-types for the individual keyboards:
We can call Chinese (Simplified) PRC, but cant seem to have it specify anything within that keyboard layout - like the Chinese ZhongMa or Pinyin options.
Perhaps I'm thinking about this incorrectly
CLASS USER
   CATEGORY "Keyboard Layout"
     POLICY "Keyboard Layout switching"
     KEYNAME "Software\Microsoft\Windows\CurrentVersion\Run"
       VALUENAME "internat.exe"
       VALUEON "internat.exe"
       VALUEOFF DELETE
       END POLICY
     POLICY "Keyboard layout"
     KEYNAME "Keyboard Layout\Preload"
         PART "Enable English" CHECKBOX
           DEFCHECKED
          VALUENAME "1"
           VALUEON "00000409"
           VALUEOFF DELETE
         END PART
           PART "Enable Chinese (Simplified, PRC)" CHECKBOX
           DEFCHECKED
          VALUENAME "2"
           VALUEON "00000804"
           VALUEOFF DELETE
         END PART
END CATEGORY

Ok!  So the best thing I've found by reg searching after selecting the subset is the following -
HKEY_CURRENT_USER\Software\Microsoft\CTF\TIP\
{81D4E9C9-1D3B-41BC-9E6C-4B40BF79E35E}  <----keys sets like this will populate depending on what you pick
For Example the following is used to enable the specific Chinese Simplified PRC Pinyin ABC input method keyboard 
[HKEY_CURRENT_USER\Software\Microsoft\CTF\TIP\{81D4E9C9-1D3B-41BC-9E6C-4B40BF79E35E}\LanguageProfile\0x00000804\{FCA121D2-8C6D-41FB-B2DE-A2AD110D4820}]
"Enable"=dword:00000001
This location will populate with keys relative to the layout subset you toggle with the checkbox.  They can be exported and scripted to run at the end of the adm or import through GPO at login.
I couldnt find this anywhere else on the interwebs.....hopefully its helpful to someone else.
