Hi @41844108
Thanks for visiting our forum. Thank you for your feedback. Please kindly note that here on Microsoft Q&A forum we mainly focus on questions about Teams for Business. For General channels, you can set up to block messages as follows:
Teams currently provides templates for teams that can be used by users with common needs or projects. Teams templates are suitable for all organizations, from small to large enterprise and education organizations. You can sign into Teams admin center > Teams > team templates.
Also, I checked for similar feedback on your suggestion in Teams User Voices. Please be patient! With requirements like this increase, the problem may well be released in the future. Thanks for your understanding and support.
