Combinatorial data in xUnit.NET?

I'm migrating from MbUnit to xUnit, and I'm trying to locate the equivalent attributes (or approach) to MbUnit's [CombinatorialJoin] and [Column].

For example, when testing common behavior of a function with multiple boolean parameters, [Column] makes it very easy to test the permutations:

public void TestMethodWithTooManyOptions([Column(true, false)] bool dispose,
                                        [Column(true, false)] bool useDestinationStream,
                                        [Column(true, false)] bool useCorruptedSource,
                                        [Column(true, false)] bool loadTwice,
                                        [Column(true, false)] bool useSourceStream) {

[CombinatorialJoin], [SequentialJoin], [PairwiseJoin] affect how columns (or rows) are permuted.

This is perhaps a correct response...

If you use ApprovalTests, you can create an xUnit.net Fact and the CombinationApprovals.VerifyAllCombinations method to run combinatorial tests.

It's not the same as using an attribute, but it's the best solution I have found in xUnit.
