Post comments in unpublished state automatically

Hi,

I 'm a bit stuck here.
I am currently working on a project using Cobalt CCK and where (Komento) comments play a huge role.

Users can post articles and they are supposed to moderate their article comments by themselves.
In the ACL you can set a user group (eg Author) to publish, edit (etc) authored content's comment.

However, moderation is only possible in the back end, so they are not able to approve comments.
Here my request:

1. Facilitate front end approval of comments by article owners.
2. Or: Auto publish and flag comments as unpublished until the article owner decides to publish them.

I really hope you can help.

Best regards,
Himgoku
