[TYPO3-dev] Append sheet to existing plugin flexform

[Peter Klein]

Is there any way to append a FlexForm sheet to the FlexForm setup of an 
existing plugin?

What I want, is to add an extra sheet (tab) of options to the tt_news 
flexform setup.

I can replace the entire sheet by issuing a:

t3lib_extMgm::addPiFlexFormValue(9, 'FILE:EXT:myext/flexform_ds.xml');

But then I have to update my flexform file everytime the oringinal flexform 
file is changed. :(
