Unfortunately there's no option to group user inputs.
In this environment load the url and user input does not means the same.
We shouldn't group this , url title and path are the same , the only different is the user input
If you select "User Input" as the default name for Load Actions you could just use the Action Namefield in the rule.
If you don't want to change the default action name, you would have to open an RFE to add the User Input to the List of Rule Parameters.
