I want to apply artistic colour effects (for example: colour substition) to sections of video and have them fade in rather than simply (POP!) appear. but I can't see any way to fade or transition to the desired effect without also disturbing the audio timeline. I do not want to cross-fade sections of video. I want the Artistic filter effect setting I select to transition/ fade into effect on the section of video...and then either fade out or transition to the next selected settings. As it is now, I can do a series of jumps between various artistic filter colour settings, but this is visually jarring. I want the transition to be smooth. Is this possible? 

There is an "Effects fades" portion of the effects list, but it seems to be empty.
