Is the same possible with Generate Blocks? I use this approach as I organize the post list displays by subtopic on parent topic pages. Therefore simply using a post list without control over the specific posts displayed isn’t a good option for me. Thanks!
Slightly better then that, if you add a GB Query Loop block, in the sidebar settings Click > Add Parameter, you will be provided a list of parameters to select from eg. Include posts where you can the search/select the posts you want displayed.
