Since Sierra permits libraries to define an alternative variable-length field tag to reference for the patron email address – see attached Admin Corner screenshot – LX Starter should either follow the same customization or at least permit its redundant definition in the LX Starter configuration.

As much as we would like to switich to LX Starter for notices, we cannot move forward until the product supports this same customization.

To be clear, we DO still store conventional patron email addresses in the z - Email field, but if the patron also/instead wishes to receive SMS notices via an SMS-as-email service, the v-tagged field as defined in Admin Corner will be the field to reference for both of those email and SMS addresses. Without the feature I am requesting, our SMS-only patrons will cease to receive notices.
