When Custom Fields is Renamed, Automatically Update the Custom Fields in Reports Prompts

Description - Currently when a Custom Field is Renamed, any report that has the Renamed Custom Field as Prompt will not be automatically updated and will generate an error in the Report (Attached Screenshot). The only way to resolve this is by manually updating all the reports prompts with the Renamed Custom Field.

Why is this feature important to you - As we have thousands of users and thousands of reports in our instance, this is important to reduce the impact of the Renamed Custom Field automatically updated in the Reports Prompts. 

How would you like the feature to work - This should be consistent as currently the Renamed Custom Fields will automatically update the Report Filters/Views/Groupings (Including Text Mode). The System should automatically update the Renamed Custom Fields in Report Prompts instead of users required to manually it.

Current Behaviour - Any report with the Renamed Custom Field as Prompt will not be automatically updated and will generate an error in the Report (Attached Screenshot). Require to manually update the report prompts.
