Enhance Email Templates with Store View attribute

While developing with custom Email Templates we need to load a language specific Transactional Email Template. For example we have a custom order approval process and need to send approval requests with translated Email Templates depending on the store used by the customer

Magento's solution for this is to have multiple Email Templates with different names and then making them configurable for different scopes in the System Configuration.

However this is quite tedious and it's hard to keep an overview about which Email Template is used in which store.

Our proposal is to add an additional attribute «Store Views» to the Transactional Email Templates.
