RemNote "Rems=Docs" Feature

I have been using RemNote for a few months now for school work.

As I start building my PKM system I have been getting used to using Obsidian and Logseq together because of its markdown editor and features like embedding websites/tweets.

In RemNote I can easily create blocks that do not belong to any specific documents/page but they are sill are in my knowledge base and function just as pages do.

Does Logseq (or any other ouliner) have this feature like RemNote?
