It would be great to have a feature where you define and manage parameters at Organization level or Workspace level. It would save us and I am sure a lots of Organizations out there where we need not go to individual reports every time any parameter is changed which is used across the board.
This would also be useful to define whether a workspace is a DEV, TEST or PRODUCTION environment. When moving the report through a pipeline it can then automatically brand a Power BI report as being production/non-production without having to download the PBIX, change the branding, then re-uploading through the pipeline.
