Show current amount of steps in a Flowbuilder

Feature Request Summary: 

When building Flowbuilder Responses, there's a limit of having 1000 steps in total in the Flowbuilder - but the admin creating the flow cannot see the step count before saving and receiving an error/warning.

Description/Use Cases: 

When building a big Flowbuilder setup with a lot of steps like we do, it is a challenge not being able to know the number of steps currently used. 
Since there is a limit of 1000 steps in a Flowbuilder, it is crucial for the one building the Flowbuilder to know this count so flows are not made in a way that cannot be completed.

Business impact of limitation or missing feature:

Not being able to see the steps count is a risk of having to rebuild parts of the Flowbuilder because it cannot be finished in the way it was planned.
