@josonodes the question itself was how you can replicate workflows between apps, which IMO was answered (you can copy paste the YML).
If you’d like to have some kind of sharing feature please create a #feature-request with as much details as possible. E.g. should individual workflows be shared, or just a globally shared config, etc.
Couple of existing related #feature-request - if one of these would cover what you want just vote there, and feel free to leave a comment:
