Default analytic account system

when I create some accounting movement , I want to be able to input automatically the analytic account depending on product or category of product. Besides I would like a different account for sales, purchases and stock movements.

Part of the functionality is done by account_analytic_defaults but only product/user/partner/campany criteria and only for sales. My point is to enhance and generalize this defaults system to more criteria.

During the input of a product in sales order, purchase order or packing list, I want the system to be able to retrieve automatically the analytic account number (sales, purchase, stock movement and manual entry) from a table depending on criteria.

Idea is to use a similar functionality, selection or ruling system currently used in list price which would allow to create accounting scheme.

Advantage is that it would use the same kind of method as in prices (so the people know how to use it) and it is a very flexible way of inputing the information.

Possible criteria to be used: product/template/category, partner/partner category, user, company, account from general chart of account.
Possibility to use a sub list as a result like in pricelist ("price computation based on").
Possible output: analytic account for sales, analytic account for purchases, analytic account for stock movement, analytic account for manual entry.
other possible output: positive/negative movement, currency, analytic journal
