CRM and Books Integration: Selling Items as a Bundle

Hi all,
I wonder whether anyone here is using, or has used CRM when synced with Books? I'm interested in the capabilities of CRM's invoicing module, and would like to have a chat with someone really knowledgable.

What I'd really like to be able to do is invoice a customer for an item called "Bundle A" which has a price of "£x". Bundle A includes several different items, and on the customer's invoice is "Bundle A", and a brief description of the service that they've bought.

But "Bundle A" isn't a tangible thing, so when the invoice syncs over I'd like it to be recorded in Books that a sale of "Bundle A" = Items 1,2,3,4 . This way, when reports are done, the items included in the Bundle A are reported as having been sold, and I can start to think about using the stock check functionality.

I'd love to know :
A) Whether this is possible
B) If it's possible, is it native functionality, or would development be required, and how complex / costly would this be.
C) If it's not possible, is there a way of achieving this another way?

Many thanks

James
