If you go to your Scribe Notes in Information, then copy the part under column Note Index, you can paste that in a message to your army, or whoever else, and send it. It should look something like this: [Scribe:224109|cbf290165f731835] Battle in Mattan Dews
I don't think an automatic send to army is very useful. It just encourages more laziness and non-involvement from players when we should be trying to engage them to interact with each other.
