Updating multiple workspaces keeping parameters the same

We have multiple reports with more or less the same queries running. The difference is each report uses different parameters. When we're making a significant change to the reports, this requires then to be done in each report (or adjust each parameter in the correct version). Make it possible to update multiple reports by publishing this in multiple workspaces (but keep the existing parameters the same). This way version control on multiple reports is manageable and new functionalities can be added easily.
