Shared-channels single post comments aggregation coming from various segregated teams (Toggle)

Hi folks,

I frequently use shared channels to post ongoing provider incidents to various teams (whether this is related to cloud outages, API errors, etc.).

Could we have a synchronization function for the comments from various teams?

The comments could be aggregated with the switch of a toggle so as not to copy-paste the same status multiple times to all teams, over and over again. And on the other side, if the toggle is not activated, we could maintain some separation. 

Please vote here. Thank you for your consideration and comments.
