Connecting layout 351 with the cms

A community member asks if it is possible to connect Layout 351 with a CMS, noting that it may be a messy choice but is good for their use-case of case studies. Another community member shares a video on how to edit Layout 351, but the original poster indicates they couldn't find anything about linking it to a CMS. A third community member then provides a different link on how to connect Layout 351 to a CMS, but there is no explicitly marked answer in the comments.
