Quick Session and Database Question

[eluser]theprodigy[/eluser]
Scenario:
Sessions autoloaded,
$config['sess_use_database'] = TRUE,
2 databases configured in config/database.php

Question:
With 2 databases configured, is there a way to tell CI which connection to use to store session data, or is default my only option?

default is your only option without creating your own modified version of the Session library
