the phrasing is a bit misleading yeah, the section plane thing is not new to 2023, nor is the tag thing. and style builder is a tool to make your own style but no, you can’t apply a specific style to a specific group in SU as Dave said.
indeed you can, there is even a dedicated section on the forum ! but it’s not easy, it takes some learning first
(ok not an actual section, it’s part of SketchUp Labs )
