Hey Johannes,

thanks for your message! You can, but not in a built in way. What you would need is to write an ad hoc datasource that fetches the trend data using the previously mentioned GetAnalyticsTrendDataMessage. Here is the documentation for it:

If you would like some more help, don't hesitate to reach out!
