Hi James
It depends on the test runner you are using to execute the scenarios. As you are using SpecFlow+Excel, I assume you are also using the SpecFlow+Runner.
Filtering the scenarios on an example level is not yet possible. It's on our backlog to add this feature.
I don't know your exact use case, but did you already looked in the Targets- Feature of the SpecFlow+Runner. This is made to execute the same scenario with different configurations.
You can filter on targets, because the target name will be part of the scenario name.
Best regards
Andreas
