Enhancement Request:Ability to Set Custom Display Names/Aliases for Column Selection Items in the New Report Studio

Request:
I would like to request an enhancement to allow users to set custom display names or aliases for column selection items in the new Report Studio.

Reason:
In the new Studio, Perspectives have been removed. As a result, we can no longer rename the items displayed in the column selection list, which makes it difficult to present user-friendly or business-specific names in reports.
This functionality was useful for improving report readability and usability, especially for end users who may not be familiar with the original technical or system-defined column names.

Additional Context:
A specific example is when creating a Column Picker. In some cases, we need to use metrics by dragging and dropping them directly from Project Explorer. The same applies to objects such as KPIs, where the items must be added directly from Project Explorer.
In these scenarios, using Insert Column to create a new column is not a suitable workaround, because the requirement is to use the original metric or object directly in the Column Picker or KPI configuration.
Therefore, we would like to have a way to rename or assign custom display names/aliases to metrics and other items that are added directly from Project Explorer, especially for use cases such as Column Pickers and KPIs.
Please consider adding the ability to define custom display names or aliases for these items in the new Report Studio.
