Group Flow steps and add labels/descriptions

I think it’d be really helpful if there was a way we could visually group together campaign flow steps, and add labels/descriptions to both the group and the individual steps.

We’ve got some flows with quite a number of steps, and in order to remember why things are the way they are I have to go document them in another system, so every time I make a change in Marketo I need to also go update my documentation.

I’ve seen some people use wait steps as delimiters but I don’t think that’s a reasonable solution.
