[Solved] editing articles that appear in multiple categories

I have a site with around 400 articles. Many of the articles appear in more than just one category. I need to be able to update an article, and have it updated in all the categories it appears in, not just the one that I updated it in.
So If "Sample Article " appears in Category A and Category B, when I update the " Sample article " in Category A - it needs to be automatically updated in Category B as well.
Thank you !

Hi and welcome

I think you miss a point, the items are not duplicated in different categories, there is only one item that belongs to different categories. So when you modify and update the article , the article is updated whatever category it is.

So this is not an issue
