As a sustainability manager, i want to set all my activity data as "reviewed" once i know that my final activities are correctly set in the system.

As a sustainability manager, you want to be able to keep track of which activity data has been reviewed and which data is still outstanding or pending. One way you could do this is by using a "tag" system to mark data that has been reviewed, allowing you to easily identify which data still needs to be reviewed. For example, you could create a "reviewed" tag and apply it to any activity data that has been reviewed. This way, you can quickly and easily see which data still needs to be reviewed by looking for items that do not have the "reviewed" tag.
