Allow all content types to have same workflow and actions (or easy way to copy actions from one content type to another)

I have a situation where I have many content types. They all have the same workflow and actions for them. It is a painful process to update each content type with the actions. Since they are all the same, it would be good if there was an easy way to either 1) indicate that all content types have the same actions, or 2) easily "copy" all the actions from one content type to another.

Another alternative would be a better interface so that all changes happen upon one submit rather than having to submit for each action. Perhaps a bunch of check boxes and a submit button at the bottom. I assume that would be a change to the actions interface, though, and not the workflow module. And, it still wouldn't be as handy as having the features mentioned above.
