3850 QoS class-map match-all?

I would like to create a QoS marking policy that re-marks packet to CS5 if the inbound traffic is SIP *and* if it is marked CS3 when it comes in.  I would have expected the configuration listed below will work.  I only found out when I tried to apply the config that, unlike other IOS devices, "class-map match-all" does not exist in 3850 3.3.x code.  It can only do "class-map match-any" Can anyone suggest a work-around config for 3850 to achieve the same end result?

ip   access-list extended ACL-QOS-SIP
permit tcp any range 5060 5061 any
permit tcp any any range 5060 5061

ip   access-list extended ACL-QOS-CS3
permit ip any any dscp cs3

class-map   match-all CM-QOS-CS5
  match access-group name ACL-QOS-CS3

  match access-group name ACL-QOS-SIP

policy-map   PM-QOS-MARKING

class CM-QOS-CS5
     set ip dscp cs5

Any suggestions would be appreciated.

I have also noticed this and haven't ran across an equivalent match-all command.  Has anyone else ran across this?

Since 3850 / 3650 IOS XE

Since 3850 / 3650 IOS XE changed the class-map style, it supports one match command per class map on ingress only.
