Here you can add, edit, or remove Assembly Rate Limit settings for the identified API Plans.
By Selecting "Synchronize Edits", any changes you make will be reflected, if possible, among all Assembly Rate Limit settings for API Plans 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.
