New Retention policy for Audit Logs

I find that the Audit logs are hardly usable on tracking device changes. I think we should be able to track the last X changes per object in addition to an age limit as well. Example...

Objects will have the last 20 changes made to them logged regardless of age and all changes made in the last 90 days.

or

Objects will have the last 20 changes made to them logged if under a year old and all changes made in the last 90 days.

If these changes can be additionally filtered by type (Auto discovery, API, User) that would be even more useful

Object will have the last 10 API/User changes to them logged regardless of age and all changes made in the last 90 days.
