Here you can add, edit, or remove Policy Injections for the identified Policy Injections configurations.
By Selecting "Synchronize Edits", any changes you make will be reflected, if possible, among all Injections settings for Policy Injections 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.
