Unsure how to assign Baseline when using Arguments

[JakenVeina]

I've got the following setup for a benchmark fixture:

public class MyBenchmarks
{
    [Params(1, 2, 3)]
    public int SomeParameter { get; set; }
    
    [Benchmark(Baseline = true)]
    public void ScenarioA();

    [Benchmark]
    [Arguments(4)]
    [Arguments(5)]
    public void ScenarioB(int someArgument);
}

I was taken aback when the benchmarks spit out...

Method	SomeParameter	someArgument	Ratio
ScenarioA	1	?	1.00
ScenarioB	1	4	?
ScenarioB	1	5	?
ScenarioA	2	?	1.00
ScenarioB	2	4	?
ScenarioB	2	5	?
ScenarioA	3	?	1.00
ScenarioB	3	4	?
ScenarioB	3	5	?

What I was going for, and had before I added someArgument was...

Method	SomeParameter	someArgument	Ratio
ScenarioA	1	?	1.00
ScenarioB	1	4	0.50
ScenarioB	1	5	0.50
ScenarioA	2	?	1.00
ScenarioB	2	4	0.50
ScenarioB	2	5	0.50
ScenarioA	3	?	1.00
ScenarioB	3	4	0.50
ScenarioB	3	5	0.50

Makes sense, in retrospect, I suppose. I could achieve this by just splitting a ScenarioC method off of ScenarioB, and getting rid of someParameter. Is there a simpler way to get these to group up?
