[nsp] Is there a way to cascade CAR and GTS?

I have a question about shaping and marking. This is what I want to do:
If traffic conforms to a certain profile, I want to mark it with
a certain precedence and transmit; if it exceeds the profile, I
want to mark it with the same precedence and shape it. If GTS
allowed me to mark packets (in the same way that CAR does), this
would be simple; but since it doesn't, is there some other
simple way to do this, e.g. by cascading CAR and GTS? Does the
"set-prec-continue" action in CAR allow me to place a GTS
"traffic-shape" statement after it and have the traffic appropriately
shaped?

Would something like the following achieve the desired semantics?

access-list 101 permit tcp 10.1.0.0 255.255.0.0 10.2.0.0
interface Ethernet0
 rate-limit output access-group 101 0 0 0 conform-action set-prec-transmit 2
exceed-action set-prec-continue 2
 traffic-shape group 101 10000000 10000000 20000000
 
Thanks
