HELP WITH QOS ON DMVPN/SIP VOICE GATEWAY

I have a router acting as a DMVPN HUB & Voice gateway Router that is connecting to my ISP for MPLS & SIP service over the same interface.
I have QoS policy-map named POLICY that is applied to the physical interface facing the ISP. Now I want to apply a LLQ QOS to my DMVPN tunnel.
I have seen that I cannot apply CBWFQ to both tunnel and Physical to specify the bandwith capacity of the link (i got error when i did this).
I contacted Cisco TAC and they told me it is not possible to implement it like that.
I believe there should be a way around this, experts what will be your recommendation?
How can i achieve qos for the sip traffic going through my physical interface to the service provider and achieve qos for the traffic passing through the tunnel?
