Timecode offset

When working on longform projects (feature films) it's pretty common to upload scenes/sections that have embedded timecode. Currently every dropbox replay comment starts at 0:00.000. It'd be very helpful (especially for comment export) to have a timecode offset for each uploaded file. So if I'm uploading a section of a film that starts at timecode 02:10:11:18, for example, the comments will begin at that timecode rather than at 00:00:00:00

Ideally, dropbox replay could reference the timecode embedded in the uploaded files to find this offset, or even read a portion of the screen (often timecode is embedded in the image) to figure out the offset. But even having a manual offset would be lovely.
