Is there a way to remove a collaborator from all tasks in a project?

[Wendy_Allen]

I was a project manager for my team, so I was the one adding all the tasks in these projects, so I’m a collaborator on everything. I’ve since changed roles, but now I’m getting notifications for alllll these tasks that no longer have anything to do with me. I tried to go through and remove myself, but it’s probably hundreds of tasks as well as sub-tasks. Is there a way to remove yourself as a collaborator from tasks and subtasks in bulk? And if not, could this be submitted to developers as an idea?

Use Advanced Search to find all tasks, where you are a collaborator:
Put your name in Search → Advanced Search → Collaborators

Then select your tasks and remove yourself from Collaborators using mass changing tool:
