Object-groups in access-lists on 3750X?

Question:

I have started to use ip extended access-lists on several 3750X-switches WS-C3750X-24S-S to filter inbound and outbond traffic on the VLANs. But it seems that the use of object-groups is not supported, is this correct? Is it really no way to group different ip-addresses into groups and then use these groups in the access-lists?

I am running sw version 15.0(1)SE2.

Answer:
It is not supported on switches.
I had a brief look at the cisco feature navigator http://tools.cisco.com/ITDIT/CFN/ and it only shows support on router type platforms - not switches.
With exception to the 6500 WS-C3750X-12S-S
