In AWS Step Functions, can you format parameter values with static string?

Question

In AWS Step Functions, we can use parameters from previous steps as inputs using the following syntax.

"Parameters": {
        "Details": {
          "weight.$": "$.product.weight",
          "unit": "grams"
        }
      }

As an example, say product.weight. is 500. Can I configure a parameter that will receive a value of 500 grams?

For example, something like this:

"Parameters": {
        "Details": {
          "formatted_weight.$": "{$.product.weight} grams",
        }
      }

Use the States.Format intrinsic function to interpolate a string:

"Parameters": {
        "Details": {
          "formatted_weight.$": "States.Format('{} grams', $.product.weight)",
        }
      }
