Split Item Income into two Income Accounts

Hello,

I'm trying to accomplish the following through this example:

Item A costs $475 for production and $25 for packaging = $500 total item's cost price.

I add profit of $175  on the production and $25 on the packaging =  $200 total profit.

Hence the item's sales price will be $700.

I pay the production vendor and packaging vendor separately, each bill goes into separate expense account (production expense and packaging expense).

I would like to invoice my customer one line as Item A = $700 only without  showing it split as Item A production = $650 ($475 cost +$175 profit) and Item A packaging =  $50 ($25 cost + $25 profit).

But in the same time I DO want to know by the end of  the month or year via P&L or another kind of reports how much I made profit from each phase separately, production and packaging. 

Is there a way  to associate an item with 2 income account? if not, is there a workaround to achieve what I am trying to accomplish without splitting the Item on the customer's invoice into two sub-items?

Thank you,
