Can I modify the Comments & Forum Feeds to "excerpt"?

[pazzaglia]

I would like to limit both my comments and forums feeds to only show an excerpt (like you can do with posts):

I want these feeds:
http://www.hippressurecooking.com/comments/feed/
http://www.hippressurecooking.com/forums/feed/

To be shortened to only show the excerpt like this one:
http://www.hippressurecooking.com/feed/

How can I do that using this plug-in?

Thanks,

L
