I am tryingo create a Field History Tracking report for All Contact.
I go  New Reports ==> Contact & Accounts ==> Contact History.

I can see the fields that I would like to report on.
I can run the report, and see a report of fields I have changed for Contacts. 
Under the "Filter" tab,  option "Show Me"  gives me only the  My Contacts drops.  I do not see an option to select  All Contacts.

Is possible to create a report that should the field changes with a filter of all contacts.
