In V11 CE, I need to have a 'handling fee' product automatically bundled with certain products I sell with the ecommerce app.  There are many product_bundle apps available on the app store, but I am looking for one that does the following:

• Calculates the 'bundle' price by adding the sale price for the individual products in the bundle together.

• Generates accounting entries as if it was a sale of the individual products, so that if they have different taxes (eg. a product that is GST FREE and the 'handling fee' that we must apply GST to), these are recorded correctly in our accounting system.

Most of the ones I have looked at just treat the bundled product as a new product with it's own taxes applied and this would not be suitable for our situation.

Does anyone know of bundle or grouping apps that perform this function?
