Enviroments MTX placement restrictions in HO

Hi, I'd like to suggest to improve the restrictions of Enviroment MTX such as Rain, so that can be placed outside the editable area of your Hideout, to properly create the desired atmosphere.

Enviroment MTXs, like fog, ash, icy and many other, should have another placement rules. At least have an expanded editable area.

To further explain this, i purchased many Rain MTX, and when trying to make my Brutal Hideout top floor rainy, i can't place them outside the Editable area. And is breaking the atmosphere of the what i want to design.

EDIT: Another idea that i came with, is maybe you sell a "Weather type" MTX, so affect the whole Hideout, in ways that distinguish Indoor from outdoor. For example in Stately Hideout (Photo 4), there is a ceiling window thath may benefit from this concept.
Thank you for reading.
