Various general attributes of the line item (like 'list price', 'total discount %' etc) can now be synced back to Dynamics 365. This is especially helpful if you sell multiple bundles as it provides full visibility of the bundle source for every product (Line Item) sold.

How to configure: Open your “Products” page, open “Actions”, click “Settings” and then click the “General Attributes” tab. Click “Add attribute”, and select the relevant attribute and where you want it to sync to. You can see this illustrated in the GIF here.
