[TYPO3-english] Get all TypoScript in BE ?

[Hendrik Reimers (KERN23.de)]

Hi,

at the moment i'm getting the TS Setup by this:

$cm = 
\TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\CMS\Extbase\Configuration\BackendConfigurationManager');
$tsSetup = $cm->getTypoScriptSetup();

But it seems that this is just getting the TS Setup of the root page. 
But i need to get the TS of any pages everywhere.

What can i do to get it from everywhere?

Thanks!
Henny
