RE: Refering to a KB item in a KB item
Hi Dennis,
Unfortunately, in addition to using a link, there is no other way to refer to other Knowledge Articles in the body.
But outside the body, there are several ways.
1. Click on the Relate Article in the command bar and we can select the relevant Knowledge Articles.

In the RELATED INFORMATION under the Summary tab, click on the article icon and we can see the relevant Knowledge Articles.

2. As I mentioned in my last answer, we can create a sub-grid to display related Knowledge Articles.
Open the form editor for the Knowledge Article for Interactive experience view, insert a sub-grid, select the entity as Knowledge Articles, and the default view is All Articles. Save and publish.
