Allow broadcast messages to be edited

Broadcast messages should have the ability to edit an existing message. For example, if a maintenance window needs adjusted slightly it is easier to update than delete and re-create.

Next steps

Do we agree on this feature? When can we implement it?

I guess this makes sense. Not a big priority though, because delete/make new works as well.

Milestone changed to 8.4

Yes, but delete/make new is annoying because I end up having to look up the colors and think about the end time again. I'm a big whiner :-)

I agree. Our organization often ends up having to change a broadcast message's contents due to work pushing back maintenance windows. Being able to quickly edit the message would be a huge help.
