Obtain ValueConverter's parameter in the fromView method


Is there any way to obtain the parameters of a ValueConverter in the fromView method?

I have a ValueConverter called RoNumber on an input:
<input value.bind="sum | roNumber:2" />

I can easily obtain the parameter(s) passed (number ‘2’ in this case) in the toView method : toView(value, parameter). However, the fromView method does not seem to be passed anything besides the value itself. Is this a bug or by design? Is there a way to obtain the parameters in the fromView method as well?

You can see how to utilize value converter in this simple example
As you can see, all of the parameters passed to the value converter in a view are logged in console.
