Combine free shipping with product or order discounts

Shopify Functions

Is it possible to offer free shipping only when a product discount or order discount created in the application is applied?
I would like to add a free shipping option to my product discounts and order discounts.

I tried this problem by rewriting shopify.extension.toml as follows but it did not solve the problem.

api_version = "2024-07"

  [[extensions.targeting]]
  target = "purchase.shipping-discount.run"
  input_query = "src/run-shipping.graphql"
  export = "run-shipping"

  [[extensions.targeting]]
  target = "purchase.product-discount.run"
  input_query = "src/run.graphql"
  export = "run"

Message log:
Error while updating drafts: Targeting multiple Function APIs is not supported.

You can currently only have one target for discount functions. Your use case is not technically feasible with functions. One alternative is to automatically add a manual shipping code at checkout with an extension (our application Stackable now does this!).
