Staff indent and staff text

@dankreider
Dan, I do know how to place text between frames.
I even posted an example in the second post of this thread:

It is a great way and sometimes very usefull indeed but as I explained to Rob Tuley I now prefer for these situations to use staff indent as it is much easier.
I only do hope that this task can be made faster in the future.

I attach an example of what I am doing, this time with the vocal part only.
