Catalyst 4500x : Shaping traffic and appliying queuing (nested policy-maps)

Question

Hi Everyone, 
I got a question on how actually I could put kind of nested policy-maps under an interface on a 4500x switch. 
This is needed because 100Mbps link connecting 2 head office locations. The 100Mpbs is a metro ethernet link and the provider is fixing port to 100Mbps speed.
Since 4500x is not supporting 100Mbps speed on interfaces, the provider's port is connected to an intermediary switch at 100Mbps. And the 4500x is connected to intermediary switch at 1Gbps. 
Hence, I need to shape to 100Mpbs out to my 4500x port. But I also need do perform queuing for traffic. The thing is nested policy-maps doesn't seem to be implemented on 4500x as in routers.
Any idea on how to workaround this? In a router world I'd do something like this: 
policy-map SHAPER
class class-default
shape average 100000000
service-policy QUEUING
policy-map QUEUING
class VOICE
priority
police 5000000 conform-action transmit exceed-action drop
class INTERACTIVE
bandwidth 20000
class BULK
bandwidth 20000
class class-default
dbl
interface TenGigabitEthernet2/1/9
description TO_REMOTE_HEADOFFICE
service-policy output SHAPER
Thank you.

I have the same problem. I wanted to do sub-interfaces with dot1q tags and nested shaper policies, but the 4500x doesn't appear to support either nested shapers or subifs. Really wish there was more consistency across platforms.
Instead of the subifs, I can simply create vlan interfaces (not my favorite method, but it works).
As far as shaping goes, the best I've been able to come up with is a custom policy that polices for the realtime traffic (i.e marked with EF or AF41, 42, 43) and everything else is matched by a custom class that matches any and sets the shape average % on the interface accordingly.  (i.e. a 10g interface shaped to a 2G pipe would get 19% for all traffic and 100Mb for realtime apps like voice and video). Not perfect, but without nested policies it's hard to do a full 8 class policy and shape each class to a specific rate.
class-map match-any REALTIME
match dscp ef
match dscp af41 af42 af43
class-map match-any CATCH_ALL
match any
policy-map QOS_SHAPE_2G_OUT
 class REALTIME
  priority
  police rate percent 1
 class CATCH_ALL
  shape average percent 19
int ten1/1/27
service-policy output QOS_SHAPE_2G_OUT
If you want queuing, then drop dbl in the catch all class and you're set. This is not ideal and doesn't do as well as a nested shaper policy. If anyone can come up with a better solution, please post it!
