Port mirroring

Greetings everybody
We are using CCR1009-8G-1S-1S+ router for out company. This router is extremely good and excellent. We are using this device for internet failover, for some servers, multiple networks, CAPsMAN administration.
We have opportunity to get device for traffic monitor - detect bad things what are transmitted. That for port mirroring is needed.
We are using SFP and Ether8 ports for WAN. Other ports are for local stuff. I would like to monitor as much ports as possible.
Is it possible to mirror 4 Ether ports or more to one port?
