while there is a nice feature "marketing cloud feed" it is only allowed to post either to "all" or to single persons. CustomerCare told me that it is not possible to share a post to a group even it is suggested in the "To" field:
i was told that this is not a bug and therefore i should raise an idea in the forum ... i did it
Request:
- allow users to post to groups (defined by the user groups in the marketing cloud)
optional
- allow users to share to their own group only, admins can send posts to all groups
