The answer is no. But the alternative is to export .fit file data through the fit file repair tool to Microsoft Access.
The fit file repair tool is controlled by pressing buttons. I was in contact with Mathias Krallmann from Germany, the developer of the fit file repair tool, several times. He is a friendly person, and he was always open to include wishes of his costumers in his updates and offered test versions with updates. He as an update tradition of 16 years.
When I got him right, it should be possible to control the fit file repair tool by scripts to avoid pressing buttons.
The structure of the fit files I tested looked not so transparent. But I think it should be possible to write scripts in Microsoft Access to process data for scientifc or biomedical purposes. In Garmin Connect this is not possible.
