I have successfully used Visio Link Shape Data to launch Cube.exe connecting to another DMS and opening the Trending App.   But I cannot figure out the syntax from docs as to how to preselect the Trend Group.

I'm leaning towards not possible and a feature request required?

I am aware of the cube:// also but that doesn't seem to get registered automatically in our clients which are managed installs by MSI, and cannot see that allows a defined Trend Group either hence using the Cube.exe /Launch syntax.

Note, within the same dms Component:Trending and ComponentOptions:TrendGroup=MBA1 Temperature does work, but this is trying to launch cube connected to a different dms
