Improve Import Custom User Data Capability

Description: As a user of your feedback management system, I want to import custom user data using the Import functionality. Problem: Currently, the Import functionality appears limited or unclear when it comes to importing custom data. This causes difficulties for users who need to feed personalized or specific data without manual input. Benefit: Enhancing or clarifying the Import functionality would streamline the process for importing tailored user data, saving time and improving flexibility for users with specific customization needs.
