Our logged-in customers would like to use one of our Custom Fields (Severity Levels) as a column heading and sorting method (eg "1 - Urgent"s at the top of the list).
A. How can we enable Customers to be able to do this (as there is no option to filter by nor add "Severity Levels" field in the screen shots below.
B. I know how to do this for my Jira Support team (via the "•••"s in the Request list view). Can this be set at Admin level for all invited/login Customers and invited Team Members?
