How do I change the default Fib Retracement parameters?

 
Is it possible to change the default parameters for the Fib Retrace tool?  I make changes using the dialogue box but they too often disappear.  I want to make them permanent so that they appear when I apply the custom indicator FiboRetracement3. mq4.  Any help would be greatly appreciated.

Note that last settings are applied automatically.
