Make Announcements Editable

It would be wonderful if the system allowed you to go in and edit a previously sent announcement without having to blast another to all users that already received the original.

Almost like a social media post. I want to go in and make modifications or I noticed something that is messed up and I want to modify it.

This would be wonderful since the announcements do not like to keep certain formatting aspects during transmission. I had sent an announcement with formatting and when my users received the announcement it was all jumbled and looked like a hot mess because it didn't keep the formatting and i wasn't aware until after it was out and then nothing I could do about it unless I sent all those users another announcement.
