easier duplicate and split video and/or batch delete
currently its easy to create longer videos than spark is meant for, while we can duplicate and manually delete slides one at a time ( horrible on long presentations), either split video into two from a slide or delete everything before or after a given slide would be much better and simple to add

If you don't want a split screen you press on what you want.
How do you make a split video have two videos???
I can't delete a specific slide, and it means i have to start everything from scratch.
