I actually used section in my template, so the merged file include only the logs part of my daily notes. I’m not sure about blocks, but probably it should work too. The only problem is that you need the block-ids to exist and to be the same in all notes (so you supposed to write it manually I guess). Then you can use blog-id instead of the section name.
Or, if you already have the list of the links, you can use even easier code to extract content, it was discussed here: Extract note A content from a link in note B and pastit down the link. Is that Possible.
