I have a TYPO3 v7.6.18 multi-site system with tt_news plugin for news.
Each site has its own news section with different categories like:
I would like to be able to choose from these categories, when creating a news item, but in the Categories&Relations (I have hidden the Relations tab, since I don't use it), I get the whole list of categories from almost all the projects (probably all, there is just a limit on how many it shows):
How can I set it to show only the categories for current page (or least a tree view, where I can see, where the categories belong to), because currently it's impossible to tell, what category belongs to which project (since the names overlap).
