I'm going through our AI Maintenance page. I have a few questions.

Employee unassigned to supervisor: there is one person who will always be on this list. She has no supervisor because she is the top person. I already have her set as ignored in the list. I wish there was a way to set get her off the list without assigning her a supervisor.

Any Training that has not be used in 6 months: Many of our trainings are used only once a year. Is there a way to change that parameter from 6 months to 12 months?

I wish there was a way to hide components of the AI Maintenance list that we just don't use: 

Some of those will always be empty. Hiding them within the list will not clear those components from the list. Ideally, if we ignore someone/something within a list, those items should not count towards the total.
