How do you find hatches with non associative boundary?

If you do "Hatch Area" and it is disabled "Associative Boundary" then it creates a new Shape on your Shape. (by Flood).

How can then find hatches in your drawing if the element is a generic Shape?. Does it have that Shape a particular property to find them?

In the case of "Associative Boundary" enabled it creates "Associative Region" so I can find them by that type of object.

In the case of AutoCAD, it does not mind if you creates a hatch with Association or not because it always create a "Hatch"  object. So if you do a query or find hatches (associated or not) you just find by "Hatch" object.
