Updating Saved Preferences Concern

My subscription page uses both First Name and Last Name in Fluent Forms. Only the first name is required (as is the email address).

When I set up Editable Primary Fields in FluentCRM Global Email Settings, both name fields are required. If someone didn't provide a last name when subscribing and doesn't want to provide one just to manage their preferences, they're stuck.

For now, my only option was to uncheck the last name field. It would help to have control over which fields are required when managing preferences.
