Statistical reports cannot be sent to the community channel, only the functionality of copy & paste is work.

This is due to a limitation on Blizzards end. Every message sent to a world channel, general, trade, localdefense, communities, requires a hardware event. Details uses a timer, so no hardware events, to make sure that messages come through in the correct order. Without a timer, you can bulk send all the messages, but it can and will come through out of order. Others will see 5,1,2,4,3 or some variation, even if messages were sent in order.
