How do I add NIC-400 Timing Closure Using Ruby API?

I have a NIC-400 configuration that has many interfaces.  Every time I add/remove an interface I need to go into uArchitecture Editor and add the Timing Closure register slices manually to each and every interface.  This is a tedious and error-prone process.  Is there a way for me to use the Ruby API so I can automate this process?  I didn't see any Timing Closure options in the Configured Component API documentation.

Or I would appreciate any advice on how to make this Timing Closure process easier.  Thanks.
