We’re not aware of any editing application that has that functionality. Anything that is done in the NLE will have to be baked into the equirectangular video file. Stationary watermarks and titles would have to be created as a separate layer by the 360 player. Custom 360 players like those used for creating virtual tours have that functionality, but it only exists within that player and likely wouldn’t translate to other platforms such as YouTube, Facebook, or Vimeo.
