Before I give up on using Compositional Layout and subclass FlowLayout, does anyone know how I can add a gap after a specific index path on a UICollectionView using compositional layout?

This presents a few challenges as I understand the API:

1. I want to add a space within a group, rather than in between groups
2. With the gap added, the items will extend past the edges of their container
3. Decorator/supplementary views can't affect layout
4. Items don't have margin, they only have inset
