You can try to map your new products to a category called "New Products" instead of marking them as new. That way you will still have a separate page for your new products but it will have the Ajax Filters on that page.
Since one product can be mapped to more than one category you will still have your new products on their original category page but will also have them on your "New Products" page.
Hope that helps!
Hello and thanks again for the answer
I am actually already doing that i use a spesific code in the ERP system which Assigns products in a correlating categories in NOP.
But i find usually that sometimes that the categories do not update as they should, and i end up end up with products that do not get assigned properly, or do not fall get removed categories.
So i thought using basic nop function and setting that every new product that gets created in NOP from the ERP system gets assigned marked as new + seven days in front could help solve my issues :)
