Currently, there's no shape data that causes a DataMiner Cube app to open. I'm trying to think of a workaround like opening a workspace or similar, but I don't think even that is possible.

The only thing that I can think of is to use the link or execute shape data and open a new DataMiner Cube (xbap from link or exe from script) with the "app=" GET parameter.

It's an interesting feature suggestion though, feel free to add it in the feature suggestions section (and link it here).
