Is there a way to add custom child object fields as columns in the Workspace list?

Summary:

Hi,

In the current feature, custom child objects can be added in the Workspace filters but we're unable to add those fields as columns in the Workspace list so that it is included in the columns when users export the records.

Is there a way to enable this so the custom child objects can be added as columns in the Workspace list? Thanks.

Users can use the custom child object field in filtering the workspace list but the fields cannot be added as columns so the fields are missing when the export the records from workspace for reporting.
