Parameterize Spock setup

Is it possible to parameterize a Spock setup?

By that I mean, imagine I have an object whose state I want to test. The object can have multiple states, but to simplify things, let's say there's one I'm particularly interested in, S1.

There are multiple ways to get the object to S1. I'm testing state, so all the tests for S1 will be the same regardless of how the object reached S1. The one thing that would differ between test cases would be the setup strategy.

One way to deal with this is to have a base test case (or "spec" to use Spock parlance) and subclasses that only supply different setup strategies.

But, given the nice data-driven features of tests that Spock offers, I got to wondering if there might be some way to parameterize the setup in such a way that I wouldn't need concrete subclass specs.

In effect, I would be saying, here's a spec, now run it with these different ways of executing setup.
