@ekatef This is what I think may be a finalized version of the PR.
Please, add your comments so that we may finalize it.

Once agreed the code, we need to finalize the documentation e.g. release_notes and config tables.
I can quickly do that but as you mainly on it, you could do that as well.
Let me know how to handle it :)

@ekatef Please revise also including a comment on how to proceed for the release_docs.
I realized that configtables are missing for build_shapes and created an issue for that. I won't be addressing that issue here so I'd proceed even without that option implemented.

Before proceeding, I'd merge all my commits into a single one by resetting and merging everything again.

Merging the PR once CI works.
I've cherry-picked your commit and the PR seems ready to go. Let me know your thoughts :)

@davide-f, thank you :) I think it looks great and looking forward to see how it works globally

Agree on that we both have to add configtables and can do it as a new PR. Touched with you suggestion on adding a release note :) But I'm also absolutely happy if you add a release note yourself as it could be much simpler
