[TYPO3-english] Override TCA of specific cType

[Mikel]

Hi there,

I created a new palette for a new content element based on TYPO3 defaults.

// flexform for pi_flexform field
$GLOBALS['TCA']['tt_content']['types']['simple_link']=array(
    'showitem'=>'--palette--;LLL:EXT:cms/locallang_ttc.xlf:palette.general;general,
                --palette--;LLL:EXT:cms/locallang_ttc.xlf:palette.header;simple_link_header,
                bodytext;Text unterhalb ,
             --div--;LLL:EXT:cms/locallang_ttc.xlf:tabs.extended'
);


How can I override the TCA for a specific field? I want to customize the 
field "bodytext" without customizing it for every cType.
Like this. But how can I extend the array to work just for the new 
content type?

$GLOBALS['TCA']['tt_content']['columns']['bodytext']['config']=array(
    
    tcaconfig

);
