Netflow 4-Byte AS numbers

I have setup NetFlow version 9 on a Cisco ASR 1001-X router and noticed that the AS numbers I receive on the NetFlow analyzer server are only 2 bytes big, so all traffic from/to AS's with a higher number than 65535 is represented in AS 23456.

Is there a way I can tweak the settings on the router so I receive 4 byte AS numbers with NetFlow?
