Thanks for the question. There is a MediaMind connector in Omniscope 2.8, however we have added the ability to execute a MediaMind custom report in Omniscope 2.9. This allows you to select metrics and group-by fields. We will be blogging about this shortly once the connector has been fully tested, however it is available to use in the latest version of Omniscope 2.9 (b559).
We have added support for DoubleClick report builder in Omniscope 2.9. You can read about this functionality in the following post: http://forums.visokio.com/discussion/2264
Unfortunately both of these new features are only available in Omniscope 2.9. We cannot add any new functionality into Omniscope 2.8 other than critical fixes because it is a release candidate, and introducing such functionality may introduce bugs.
I only ask because I am using 2.9 and using those new features already for some reporting but with the server machine being set up, IT will only allow 2.8 to be installed on it and not alpha software.
