Creating Multiple Dunning emails for multiple product

We have multiple products (brands) and we would like to be able to create multiple notices by product (brand).  It looks like we're allowed only to create general generic notices that have to cover all the brands.  It would be nice to be able to create notices by brand and be able to track the activity by brand.  Also would like to see what payments are received by invoice and by brand.  We can only see what payments came in by invoice number but not by the brand.
