default templates override per list

[naxey]

Is your feature request related to a problem? Please describe.
When changing the default email-templates like this it changes them for all lists and not via the ui.

Describe the solution you'd like
A feature to overriding the default email-templates per list.

When creating/editing the list we would have a menu to select which defaults to override with which templates.

The templates to override the defaults would live with the other templates in the campaigns > templates menu. Maybe with a different type.
