I have interest in this tool to add sessions too! The story goes like this. I'm having trouble adding gauges to my kart racing. A gopro hero6 writes to chapters and when I try to join in dashware it does make a mistake, however, it extracts the information in the form of a separate .csv file in a folder. Would it be possible for the tool to allow you to join these .csv files in sequence to create a single telemetry file? Sorry for my terrible English.
