I have my nodes set to publish at scheduled times using the http://drupal.org/project/scheduler module. I'd like it if the "send action" (part of http://drupal.org/project/simplenews) on the node moved from "don't send now" to "send now" when this action happened. Anyone know of a way to do this?

I know that simplenews has some actions accessible through admin/settings/actions, but I haven't found one that solves this problem.

Suggestions appreciated. Thank you.
