If the utility is created in .Net, then change the utility to use Client Side Object Model of Project (CSOM) to loop through all the tasks and set the status manager of each task to the project owner. https://blogs.msdn.microsoft.com/brismith/2018/05/25/project-online-setting-a-status-manager-with-csom/ gives you the code to loop and set the status manager for each task. There is no one step to change the status manager of all tasks.
