1. Is this request related to a challenge you're experiencing? Tell me about your story.

When migrating my DSL file from the dev environment to the production environment during an upgrade, I would like to reuse the existing 'API Secret key' so that my downstream services do not need to be updated.

I would like to customize the 'API Secret key'.
