Category pages with Query Loop block

I would like to use GBP query Loops to display all the post of one category in a page. Now I am using Yaost SEO to display the categories in different pages, this is a simple but limited solution.

I have read in the GP forum that the next GP Premium update, will be adding a new Element Type that allows to replace the Theme archives with those GBP Query Loops. When it could be available this new feature?

If I don’t want to wait for this new feature, do you have an example of filter I could use, on my custom class, in the grid of the GBP’s query loop block?

For example, I think that the core of the filter, to display all the posts of the category with id 4 in the GBP’s query loop block, should use this code in the filter:
$query = new WP_Query( array( ‘cat’ => 4 ) );

But I don’t know if this is the right way, and/or if I must use the Query Loop’s Toggle “Inherit query from template” (Toggle to use the global query context that is set with the current template, such as an archive or search).
