Feature description

Most of my flights are > 10 minutes so files are split.

Is it feasible to add support for "joining" of files to produce one final output?

I have produced separate files and tried to join using apps, but they have not been very successful. Usually errors playing.

Many thanks for your time and support for this. Appreciate how much effort goes into the tool :)
