Feature Request - Ability to set css class from gutenberg block editor

It would be nice to be able to set a css class for a form from the gutenberg editor. For example, atomic blocks provides and option to add a class in the advanced settings for their blocks.

I realize that it is possible to add a classname to a form from the form’s settings page, but adding the functionality to the block editor would make it easier since all the UI settings would be in one place.
