Default Auto-Fill for Blank Resource Fields on Import

Feature Request: Default Auto-Fill for Blank Resource Fields on Import

Summary:
Enable the import process to automatically populate blank Resource fields with a predefined default value. This ensures imported records remain complete and consistent even when the Resource field is not provided in the source data.

Problem Statement:
Currently, when a Resource field is left blank during import, no value is applied. This can result in incomplete records, additional manual cleanup, and inconsistent data across the system. For teams importing large volumes of data, this creates unnecessary effort and increases the risk of errors or missed assignments.

Proposed Solution:
Update the import behavior so that when the Resource field is blank, the system automatically fills it with the configured default value.
Only apply the default when no Resource value is provided in the import file, so explicitly entered values remain unchanged.
Ensure the default value is drawn from the existing field configuration or import settings.
Provide clear validation or import messaging so users know when a default value has been applied.

Benefits:
Reduces manual work required after imports by automatically completing missing Resource values.
Improves data consistency by ensuring records are populated with a standard default when left blank.
Minimizes import errors and follow-up corrections for large data uploads.
Creates a more efficient and predictable import workflow.
