Grouping for Actions

I think it would be very useful if in the list of Actions you are able to categorize with a number, color, emoji or keyword, all the sub activities that are related to a dependency or condition.

Considering that the list of Actions in a pushbot is displayed in a linear way, and in many times you add dependencies that creates multiple branches in the flowchart. It would be easier to read if you can group these Actions.

So for example, the moment that your flowchart splits in 2, all the Actions for the first split would be coded with a number 1 and all the Actions for the second split will be coded with a number 2.
If there is another set of sub Actions then these can be coded as 1.1, 1.2, 2.1, 1.1.3, etc.

Or if not, that you can manually add a color to the Actions so can manually categorize them.
