Create custom Themes based on existing assets and styles

So, there is already a great lot of assets and different styles , and i often want to mix the room and and asset generation but while keeping the main style (Walls, Floor, …) consistent.

For example, i'm trying to create a "GuildHouse", and i have to mix different themes and styles to get the kind of room i want : Castle Style overall, but with Mansion Rooms inside.

This is annoying since i have to rework Walls, Floors, and a lot of assets generated.

It would be great to be able to create a Style / Theme "Stone GuildHouse", and setting the allowed Floors & Wall types, then re-use room generation from other themes and customize them (select allowed or unallowed furnitures for the room for example). Some part of it will probably difficult to implement, but this would allow people to really use the tool however they want and share custom Themes or Room Generation Settings.
