[TYPO3-ttnews] EXT:news, Two plugins, don't display news already displayed

[Lorenz Ulrich]

Hi everyone

Is there a possibility to prevent duplicates if I have more than one 
news plugin on the same page? (EXT:news, not tt_news)

So if I got a news plugin in my main column displaying a single item, it 
wouldn't appear in the list view in the sidebar.

I'd appreciate any help.

Best regards,

Lorenz
