Hi @pnikonowicz , Thanks for submitting this.

❓ Can you provide steps so I can deploy and test this behavior?
❓ Can you provide more information about why this is needed now, but was never needed before?

[ameowlia]

✅ read through code
✅ ran tests locally
✅ deployed code
✅ since bpm.yml template tests didn't exist before, I manually checked with a cf-d deployment that the configs didn't change.

Holding off on merging until the pipeline is green again.
