I also need this. I haven't been able to get this to work and want my videos to be more dynamic.

I think an awesome and easy way to do this would be how we make cuts in the script now:

/ - normal cut

/J/ - J cut

/L/ - L cut

I absolutely need to be able to do these kind of cuts as well. Is it happening?

This is kind of a big deal, today I wanted to do a J cut but couldn't figure out a way to do it with Storyboard.
