Exclude categories in Flex Loop

Hello,

I like how one can add filters and sorting to Flex Loops. However, other than with Flex Blocks, I can not exclude categories from showing in the Flex Loop.

Is there a way to do that?

Like let’s say I have a category for blog posts (1) and a category for news (2). I only want the Flex Loop to show posts from category 1, but not from 2. How can I do that?

With Flex Blocks it’s easy, simple add – and the category id, however I can’t seem to find a similar option for Flex Loops.

Thank you!
Dominik
