Guidance on annotation: Pre-composition vs. Modifier Post-composition (e.g., Episodic Vomiting)

[lagosproject]

I am seeking guidance on the standardized way to handle clinical descriptions that involve both a phenotype and a temporal modifier.

Example: "Vomiting becomes episodic"
Option A: Use pre-composed term Episodic vomiting (HP:0002572).
Option B: Use Vomiting (HP:0002013) and add Episodic (HP:0025303) as a modifier.

Question:

1. Is there a strict "Best Practice" for when to request a new pre-composed term versus using existing modifiers?
2. From a data-standardization perspective, does HPO recommend always using the most specific pre-composed child term when available?
