What is the best practice to flag a plan WI as being built/deployed in multiple environments?

If a Plan WI has multiple execution Task WI's that are used to check-in code, the build result shows only the Task level WI IDs' in the "includes" attribute and not the parent Plan WI.
If those execution WI's are built/deployed to multiple environments, what is the best practice to capture that information in the plan WI ? This information will be useful if a business user wanted to know which environment a given plan WI was built/deployed for testing purposes? Is it a good and simple practice to add a tag to the Plan WI as being in DEV_BUILT, QAT_BUILT, UAT_BUILT ? Please advise.

Thanks
