Guitar notation: Barré

What is the quickest way to enter the barré sign in guitar notation? Usually it is a C or a B plus a Roman numeral that indicates the position. Sometimes there is also a vertical line for the number of strings and a horizontal line for the duration. Any hints would be appreciated. I have Dorico 5 pro.

There is a very helpful thread from 2021 which may be interesting:
