New feature for users

Estimated Anton and contributors, i´d like to know if every user could select (or admin assigned better) its own gateway provider (own infrastructure or external supplier), i think it should be very interesting so you could offer to each user the most adecuated service supplier. I´m a newcomer to this project so i´m begining to watch the database relationships, php, etc so i don´t know the complexity to add this new feature.

Edit: -> Ok, Route SMS outgoing is the feature i was looking for.

Thanks.
