Add a field to multiple content types at once? I want to add a field to multiple content types at once, and configure it for all of them at once as well.

Reason being is that I have many content types, all of which need to be updated by adding this new field to each.  This field will be configured the same for all of the content types as well.  I have to repeat this process of adding and then configuring the field every content type I want to add it to, and it gets arduous after a while.

Is there any way to do a mass add/configure of a new field to many content types?
Broad lines using the Features module could be:


Add the field to two (to see the pattern) content types by hand
Create a Feature including field bases and field instances for the newly created fields
Edit the created module multiplying the field bases and instances to all content types needed
Enable the edited module
