Keep TestCase attributes on separate lines during reformat?

[7.1]

When I use my code cleanup profile, I go from this (NUnit):

Test]
        [TestCase(1)]
        [TestCase(2)]
        public void Test1(int val)
        {
            
        }

to this:

Test, TestCase(1), TestCase(2)]
        
        
        public void Test1(int val)
        {
        }

Is there some setting I am missing to check/uncheck to keep the TestCase attribute on each line?
Thanks.
