Merge functionality from Engagements and Knowledge Center for consistency and improved user experience

There are discrepancies between the fields and functionality available on the Engagements page versus the Knowledge Center. For example, on the Knowledge Center page, we can see the Last Updated field, but this field is missing and cannot be added to the Engagements page. Alternatively, we are able to launch engagements directly via the Status field on the Engagements page, but have no such functionality from the Status field on the Knowledge Center page. 

In addition to bringing in additional fields that are relevant, such as Start/End dates or Used In as suggested here, it would be really helpful to see some consistency between the Engagements and Knoweldge Center pages in PX. Furthermore, enabling the ability to selectively surface additional fields in these tabs would be awesome.
