Question: how to create a test hiearchy from multiple files?

I'm creating a hiearchy using nested sections to group tests together in Visual Studio, but sections in multiple files can't have the same name. What's the correct way of doing this? or am I stuck having all the tests in one file?

````
TEST_CASE("SomeBigModule")
{
SECTION("SomeGrouping")
{
SECTION("SomeSubGroupPerFile")
{
SECTION("MyActualTest1") {}
SECTION("MyActualTest2") {}
}
}
}
