Hi Thumy,
As you can see, Unsub isn't really designed to handle packages in that way but in the past what I have done for other bundles of titles was to split the cost of the bundle across the individual titles. If I had list prices from some source for the individual titles, I would sum those up, and then compare that with the bundled price, and just scale all of the individual title prices down by that factor to get a new list price.
But to be honest, I've usually done this outside of Unsub. Alternatively, I've just used Unsub to get the OA information, etc. for these titles (you can insert list prices, or just make up prices, since you won't be using the Unsub CPU for this) and then do a manual analysis, using the same formulae that Unsub would use, to get some effective CPU numbers for each title, etc.
But interested in other suggestions.
Best,
