It would be helpful to have a separate "Preferred Last Name" field for constituents who go by a different last name than their legal last name (which lives in the "Last Name" field).
Currently we keep the preferred last name in an Alias. This poses several challenges, including:
Inability to use the preferred last name in an Addressee format without involving the free text option
Preferred last name not displayed on constituent record
Difficulty updating names properly during imports
