We are building a Visio to show an end-to-end view of a Video processing chain.  The overall display does not port well to the Dashboard view at this time.  We also have a popup Visio page for more detail where we show 4 parameters trend lines based on the associated selected service.  We like how the trend display looks and operates on the dashboard UI better (showing the readings as the user hovers across the trend line), so we were planning to build a Dashboard page which shows the 4 trended parameters then link the trend dashboard page URL to a Visio shape for the popup display.

The question is, since within Cube we are setting a variable to pass the IDX of the row to the trend data shape, is there a way to pass this variable to a Dashboard and use it as an indices for the trend display?  Otherwise, we will have to create multiple instances of the same dashboard for each user selectable service using the variable in the dashboard URL referenced.
