Would love to see the option of multiple fade points in the segue editor. As a 2 point fade doesn't sound great when the music track is as loud as the sweeper as at the end of the fade, you can barely hear the sweeper. I hope that makes sense
It wouldn't really be possible in the near future, because multiple fading points will require lots of work. You can try using the crossfade shapes feature: https://manual.djsoft.net/radioboss/en/fading.htm - use the parabolic up shape, in this case the volume quickly declines at the start and slower towards the end.
