Does anybody have a good example where they've replicated the Transaction Score within a given app to a dashboard that can be shared?
I am afraid you cannot see transaction scorecard as it is in dashboard.
However, you can always create a dashboard using any metric from metric browser.
That is unfortunate. This seems like a very modular and valuable option that would provide not just the NOC teams (1st and 2nd level) quick Business Level views from a per app scenario but also a potential complete roll-up of all apps in the company to get that full "hows my business running" Ops view. Additional to that it would provide scenarios where specific LOB's and Business units a single view of their test applications, QA, production, etc.
We have an enhancement request raised already to address this. This request is still in PM queue and hence we are not sure regarding the timeline of this.
