Hello, I am also very interested in this feature. Will it be ready anytime soon?
The reason why it would be very useful to me is that I fly and film using a drone a lot and drones often save their current location in an .SRT-file along with the video. And then when you apply for permission from the surveying authority to distribute the video to the public, they want this geo-location-information. But if you cut away useless footage that you never intend to use with e.g. Bandicut before sending the files to the authority, the .SRT-file has suddenly become useless because it no longer matches the video. So if the .SRT could be cut into a separate SRT-file for each video file, that would be a super-useful improvement of Bandicut to me.
