Is there a way to change the sort order of existing Contacts

[Doreen]

I recently gave an end user a new system. Now her contacts show up as first
name, last name when she is composing a new email, clicks on To. Does anyone
now how I can correct this for her automatically? I already tried doing this
in Contact Options.
