Can I change the key of key only artifact in step instead of template?

[link89]

I am building a workflow have the form of A -> B -> A -> B -> A -> B

What I hope is, the first time I run step B its output artifact should use the key steps/b/iters/0,
and the second time it should become steps/b/iters/1 and so on.

An idea way is all step B can share the same template and set their own artifact key.
But I am not sure if it is possbile to do so as I don't see any example to config output artifact in Step

I mentioned in your other discussion but an example Workflow is really useful when asking questions. The issue templates require one, but unfortunately GitHub does not have discussion templates 😕

This sounds like a prime use-case for parametrizing your template. For instance, you could use key as an input parameter and then have your template use {{inputs.parameters.key}}.

I am not sure if parameterizing is the right anwser. Here is an example, there are two steps using the same template, what I want is to put the file generated by the two steps to different key.
