HI @sliu-circle, YAML anchors and aliases do not directly support exclusion or negation. YAML anchors (&) and aliases (*) are primarily used to reuse and reference nodes within the YAML document.

You can however define an anchor that includes negation patterns instead

not_part_a: &not_part_a
  - '!pattern_a'
not_part_b: &not_part_b
  - '!pattern_b'
part_c: 
  - *not_part_a
  - *not_part_b
