Stitching watch folder on encoder

I know this was originally posted a long time ago but I would also really apprecicate if someone could help with this function? I work as an edit assistant with producers who would like to look at rolls of rushes from the day but would like it as one file that they can easily scrub through. I know that Encoder already has the ability to add a timecode so it would be good to be able to add several files to a watchfolder for it to then stitch them together and add a timecode.

I realise that there might be a diffiulty in getting the watchfolder to understand when you've stopped copying files into the folder for it to then start stitching. Maybe this is the main reason why it's seemingly not available...
