per the dialogue in this product question (View Process Accelerator permissions | Community) while the owner can be seen against an individual process, and the repo can be filtered for the content belonging to one owner, there also needs to be a way to see all processes owned by an individual across all repos.
When someone retires or leaves a company all of their content needs to be re-assigned to a new owner or owners, and it would be great to make all their content visible in once place. It would be even better if there was a way of being able to make bulk changes in ownership so each document doesnt have to be individually changed.
