"Details view" widget in Editor utility widget doesn't allow to select actors that are in sublevels

I’ve made a editor utility widget where I need to select some specific actors in a scene, like so:
image

The problem is that if the actor I want is in a sublevel, even though it is listed, selecting it will set the parameter to “none”:
image
In this case directionallight2 is in a sublevel, while directionallight in the persistent level

Is there any way to solve this?
