While this level of granularity is not available in the current platform, there are a couple of options available to you if this is a feature you are interested in.
1. If you would like to see this feature added to a future release I would suggest submitting an idea to the Ideas for Jive space where members of the Jive Community can vote on ideas they like to help raise awareness with our Product team. If you do not yet have access to this space, you can request access via Are you a customer? Request customer-only access today
