Here you can add, edit, or remove Rate Limit Definitions for the identified Rate Limit Definition Groups.
By Selecting "Synchronize Edits", any changes you make will be reflected, if possible, among all Rate Limit Definitions for Rate Limit Definition Groups having the same name within the same domain, unless the changes are being made to newly added rows.
New rows are treated as their own group. This is to protect existing values from being arbitrarily changed to blank values found within new rows.
