I have a senior person who is leaving our company and I need to re-assign ownership for 50 or so Security Policies and Internal Controls to their successor.
The Bulk Edit doesn’t let you do this 
I have to change the owner manually for each one individually. This is taking so long to do that I thought I would spend an extra 3 minutes moaning about it here too hahahah 
ahhaha … listen next time someone leaves you ask them to do the clicking !
internal reference to multiple other bulk edit related inconveniences:

I ran into another limitation of bulk editing today -
in the Internal Controls module, it does not seem to let you do bulk editing on any fields in the Audits or Maintenance tabs of a control? Just the fields from the ‘General’ tab.
This is meaning that I have to manually edit about 120 controls one by one instead of in bulk, when I wanted to change an assignment in the Audit tab. 
yes, bulk edits are a complicated matter, this was on the roadmap we’ll try to do something as part of the ux/ui
