Settings - Default TRACK NAME - Settings - Import/Export - Format of the FILENAME
There are only 3 options for Default track name: Date (Local), Date (ISO 8601) and Number. I suggest adding 4th one Date (Custom). It would open "Format of the track name" window where you can construct track name with similar variables as in Import/Export - Format of the filename window. Such as
{date}, {time}, {category}, {uuid}
BUT in addition I suggest the following variables to be added to both dialogues: {year}, {month}, {day}, {hour}, {min}, {sec}, {gmtday}, {gmthour}, {gmtshift}. Why not even {duration} and {distance} for export dialogue (although they are less important)
With those you have complete freedom in choosing format for training names and export filenames
