We have created channels for specific features and would like to be able to only get updates in the channel for a specific Epic. We have one huge project for all of our development efforts and feature work is done in Epics (and even Stories for smaller efforts), and I only see where I can connect a project; that would just spam a channel to where no one would use it. I see that I CAN restrict updates to certain types of issues, but that is still not practical; every epic or story is still way too much noise.
