Hello, I would like to ask if there is any way to use “double” brackets as shown in the picture. I only see the option to use one bracket and one brace.
Unfortunately not.
What you highlight in your picture are called (double) “fine brackets”. This type of bracket doesn’t exist in the Score Editor and has already been requested, hoping for its addition in a future version. Furthermore adding the possibility of doubling those brackets is a good idea. 
Thank you Maestro. I will have to draw manual lines for this …
It is what it is
