Hi Ronan,
I guess it may tough, but each report is specific and containing specific data that ChatGPT may not know.
For example if i want to analyze a report specific for CO2, i may want my default prompt base to ask ChatGPT to turn the data into a table report comparing with a car consumption and a flight, so that I can easily copy/paste it. And i don't want to re enter the prompt again in ChatGPT.
And that would be the future of Matomo. The full UI, would be a set of customized prompts for each report. The work of the web analytics would be about writing those prompts.
