Updating Sequences

Is there any way to update the emails in a sequence after I make changes to one of the steps? It drives me crazy that it will only update for future contacts that I add. I used to use Groove for a similar use case and it updated no problem after I made changes.

Similarly, when I have an enrolled contact with a mistake in the name, I have to remove them and re-add in order for the change to take hold. It doesnt make sense to me at all and adds a lot of time and effort to get around this.
