Thats is a good idea , and would be a bit of a time saver.
Do you get the option to export as 'save as' and give a custom name , or is there restrictions preventing this ?
.., another workaround could be to just rename the file once it is on your computer.
If it was loaded into a Daw , You can always use : The
tap to tempo feature , and that would instantly let you know the tempo is
(ie; you tap the tempo button along to the beat (1 or 2 bars is enough) .., and the DAW calculates the tempo for you)
