When Users are deleted from the platform on leaving the team (or business), all Assets, Tasks and Campaigns are orphaned, and there is no way to bulk view or assign them - you have to go into each one individually and re-assign it.
As there is no ability for Assets, Tasks or Campaigns to be owned by Teams and not individuals, and we have certain Users who own thousands of Assets, this is a potential massive headache in the event this user leaves, or changes roles.

Please introduce better tools for re-assigning ownership of items as opposed to everything having to be on a one-by-one basis.
