Create custom hierarchy on emails in Assignee dimension

I am trying to create custom hierarchy based on email, I have a solution where I import an excel file with names and groups but as names are not always consistent and Jira, or jira admin, seams to handle it a little different with uppercases sometimes.

example in the picture work fine but I would like to change the name to email

I have tried changing the advance settings without luck

Thanks for help

You may adjust data from the source by adding a custom JavaScript code, for instance, to align lower/uppercase usage pattern. Read more about this options in documentation: Data mapping
