One-time Siri Spoken Hints for Intent Parameters

I have implemented a custom intent that has several parameters. One of the parameters is called "dimensions". I would like to give the user a hint on what to say to respond to the Siri Dialog Prompt for the dimensions parameter. For example, if the Siri Dialog Prompt is "What are the dimensions?", I would like to have a one time prompt that says "What are the dimensions? You can say something like 2 x 4 x 35 inches". Thereafter, I would like to fall back to having Siri only say "What are the dimensions?". Is this possible?

I think I came up with a solution. I just added a parameter that gives the hint on the first attempt to prompt the user for a value. After the hint is given, I always return success so that the hint prompt is no longer given. I'll probably let the user have a choice as to whether they hear the hint again.
