Is it possible to inject data from AsyncInitialized field with only one call to InitAsync occuring?

[TheRumle]

I have a situation where I have data from an IAsyncInitializer data source. I want to use that data as input for tests. For instance

public sealed class ContainerBasedTests
{
    //Docker container
    [ClassDataSource<Container>(Shared = SharedType.PerClass)]
    public required Container Container { get; init; }

    //Enumerable from container
    public IEnumerable<Func<IMyService>> Executions 
        => Container.TestExecutions().Select(e => new Func<IMyService>(() => e));
    
    //Inits many containers because each value from Executions inits a new container. Might be bug?
    [Test]
    [InstanceMethodDataSource("Executions")]
    public async Task TestElementFromContainer(IMyService service, CancellationToken token)
    {
        var entity = await service.ExecuteAsync();
        await Assert.That(entity).IsNotNull();
    }
}

I think I'd need to expose a new interface like IAsyncDiscoveryInitializer which behaves the same as IAsyncInitializer but runs at discovery time

@TheRumle Try v1.5.0 and use IAsyncDiscoveryInitializer
