Load posts from different categories

Hi there and thanks for your great plugin.

I’m in a situation where i need to load posts from different categories than the landing post.

Eg. If the landing post is in category A, I want the rest of the posts that are loaded after, to be from different categories than A (ideally I want each and every one to be from different categories but I’m not sure if that’s possible in general without multiple queries)

Important notes:
-The website is multilingual and the languages are top level categories which have second level subcategories (eg. Top level ‘en’ category has subcategories cat_a_en, cat_b_en etc, top level ‘de’ category has subcategories cat_a_de, cat_b_de etc)
-Due to the language issue, I would like to load posts from the same top level category but from different subcategories
-I use the previous post addon as well and my current shortcode is
[ajax_load_more previous_post=”true” previous_post_id=”‘.get_the_ID().'” previous_post_taxonomy=”category” seo=”true” post_type=”post” post_format=”standard” posts_per_page=”4″ max_pages=”10″ scroll_distance=”-1300″ transition=”none” ]

Is there a way of accomplishing what I need, regarding your plugin?

Thanks,

Manos
