Design System Instance Swaps

Hey everyone! I’m working on a design system and encountered an issue with preferred instances. For example, I have a list row component that contains left and right side content. For each side, I’ve created and linked some child components, using an underscore (_) symbol for naming.

After publishing my library and inserting the component in another file, I’m unable to find the preferred instances. The dropdown opens and shows the entire list by default, but navigating through the folders doesn’t display anything specific.

My goal is to make only the main components visible in the ‘Assets’ panel, not their individual parts. I assumed that if these “child” parts are hidden when publishing but set as preferred instances, they would still appear in the component property swaps. Is this approach incorrect?
