Hi Darren,
This is supported :)
Cisco CME 3.2.1 and later versions support the creation of multiple AA services that feed into a single call-queue service that manages up to ten ephone hunt groups (individual call queues). Each of the AAs can be set up to use different options or to reach different hunt groups, and AAs can also share hunt groups. For instance, you can have three AAs that each use three hunt groups, or you can have five AAs that share some of the ten hunt groups, or ten AAs that each use one hunt group. This flexibility allows companies to create different automatic-attendant treatment for different classes of callers.
For example, you can set up an AA in interactive mode to answer calls using a prerecorded message that offers various menu choices to callers. One type of menu choice is to allow a caller to press a digit to be connected to a department or service (hunt group). Another type of menu choice can allow the caller to dial a known extension number directly.
Alternatively, you can set up an AA in drop-through mode, a new feature with Cisco CME 3.3, which is described in the "Drop-Through Mode" section. An AA that is set up in drop-through mode transfers incoming calls directly into a call queue for a hunt group without allowing any interactive choice by the caller. A prompt is optional in drop-through mode. When you configure multiple AAs, each AA can be independently assigned to interactive or drop-through mode.
When you set up multiple interactive AAs, separate welcome prompts must be recorded for each AA. With multiple AAs, the welcome prompt is used to inform callers about the menu choices that are available to them.

Hope this helps!
