Nested Audio (Grouping Stems)

This feature request ist related to a broader idea i have in mind:
Music Stem Mixing & Remixing features – Enhanced A... - Adobe Product Community - 15453030

To keep the timeline clean, it would be great if we could nest/collapse stems to a single clip. Editors could expand the group only when needed to adjust individual stem volumes or apply effects. This would reduce visual clutter while maintaining flexibility.

Another way to solve it would be to have one nested clip but give the stems seperate faders.
See epidemic sound:

Integrating stems with Essential Sound features could allow dynamic control over the energy of a scene. For example, reducing the loudness of high-frequency stems could soften the mood, while boosting rhythmic elements could increase intensity. It would be amazing if I could design a crescendo for the intro (think of YouTube tutorials) and then start the main part calmly.
