Adding a field to the Edit Role screen

Content (required):

Hi,

My client needs to add his description to a predefine role,

As we know we can't edit the role of a predefined role

He thought maybe add a Flex field to edit the role screen

Please refer to the print screen attached

1. I would be happy to hear from you a solution for this need

2. Can an FF be added to edit the role screen?
