Update Forecast - Ability to hide options that will not be used

Background:

I am referring to this feature. I understand that this feature is still in beta.

When you click 'Update Forecast', you are able to choose several types of forecast options (it used to be 3 options as shown in the KB page, but not it appears to be 2 options). 

Request:

I'd like the ability to hide the options that you do not expect your team to use. So in our use case, if we don't want our team to use "Retain future planned work assignments. The total work estimate may change.", then we would like to be able to hide that option.
