Hello @QobuzCI, 
Thank you for the feature request!
I was wondering if you could take a look at a similar request here.
We have a solution that could be useful for you, it is called the utility workflow. Basically you can create utility workflows simply by adding an underscore at the beginning of the workflow’s name. You can read our DevCenter article about it here: https://devcenter.bitrise.io/bitrise-cli/workflows/#utility-workflows .
Please let me know if you have any questions, we’d be happy to help!
