Upload only constituent IDs and email addresses

For GiveCampus constituent data and imports.

For ID lookup/return mapping, the Constituent Identifiers screen offers Upload Multiple Identifiers. This is separate from importing complete constituent records. Use its current template: the import expects a header row, the constituent ID in the first column and email in the second column; it reads those two columns by position and skips a row if either is blank. Names are not required in this two-column path.

Confirm identifier formatting, including leading zeros, before upload. This creates identifier/email mappings; it is not proof that a complete constituent profile or CRM gift history was imported. If a screen insists on names, confirm whether it is the full constituent-import workflow instead.
