Once imported, Descript will notice if the files have a similar duration and will give you an option to combine them create a Sequence.
Frequently Asked Questions
Why does Descript say "No Sequence at Playhead" when I try to edit my sequence?
A Sequence is created when you combine two or more audio tracks into a Multitrack Sequence. This message occurs when your playhead is located over a standard media file that is not a sequence file. You can tell if your clip is a sequence file by the sequence icon in the upper left-hand corner.
