Question about CBWFQ & Multicast

Is it possible to do CBWFQ for a multicast group?

I created a simple test environment:
        R1--(s1/1)--R2--(e0/0)--R3

I'm using multicast group 224.3.2.1 generating multicast traffic from R3
to R1 (pings 224.3.2.1 and R1 is replying)

I have defined my CBWFQ policy that mark the corresponding packets and
class-maps but I dont see any multicast traffic matching.

What am I missing?

R2#sh policy-map int s1/1
 Serial1/1

  Service-policy output: MQC

    Class-map: R3-TELNET (match-all)
      416 packets, 18354 bytes
      5 minute offered rate 0 bps, drop rate 0 bps
      Match: access-group name R3-TELNET
      Queueing
        Output Queue: Conversation 265
        Bandwidth 10 (%)
        Bandwidth 154 (kbps)Max Threshold 64 (packets)
        (pkts matched/bytes matched) 18/792
        (depth/total drops/no-buffer drops) 0/0/0
      QoS Set
        dscp cs6
          Packets marked 416

    Class-map: MULTICAST (match-all)
      0 packets, 0 bytes
      5 minute offered rate 0 bps, drop rate 0 bps
      Match: access-group name MULTICAST

R2#sh access-lists

    20 permit udp host 224.3.2.1 any
Extended IP access list R3-TELNET
    10 permit tcp host 3.3.3.3 host 1.1.1.1 eq telnet (416 matches)
