Pinned Banner/MOTD Feature

I think a feature similar to Instagram Live's pinned message feature would do a ton of good on medium/large servers. The current channel descriptions and pinned messages are a little inconspicuous and missable, and it would save a lot of time for a mod team in terms of simple reminders or setting a daily message. The message could be customized to either be permanent, be dismissed and not show up again, or pop up every time someone accessed a channel.
