Customize return values from API call in a Path Use Case

When a process takes a long time to run, not only may it cause a time out, but it is irritating for the user who has to wait.
In order to alleviate this, it is nice to return a message to the user saying something like:

Your job is in progress.
This can take a few minutes.
Don't wait around.
We'll pop up a message to let you know when it has been completed

Optionally, you might not need to return a message at all.

Then, later, you can use an Event use case to return a result

Here is an example of such a use case:

The message is possible in a Query Use Case, but it is not possible in the Path Use Case.

Could we make it so the Path Use Case works in the same way and have the added option (to both use cases) of not having a response at all.

Thanks.
