Substitute variables in step title in report

[asos-neilsyrett]

I have a method that looks like this:

[Given("I create a customer with {0} addresses")]
public void GivenICreateACustomerWithAddresses(int addressCount)
{ }

The report shows this as:
Given I create a customer with addresses 5

I would expect the variable value to be substituted into the step title and look like this:
Given I create a customer with 5 addresses

Seems to work when using it like this:

[Given]
[StepTitle("I create a customer with {0} addresses", includeInputsInStepTitle: false)]
public void GivenICreateACustomerWithAddresses(int addressCount)
{ }
