resources.load question

is it possible (it seems not) to load all assets in a folder without loading any assets in a subfolder?

Its not vital but i think its cleaner and more organized for my project

for example

lets say I have a BaseCarModels folder

then inside that Folder I have

BaseTruckVariants folder

and

BaseVanVariants

now that makes sense to me, i have a folder with my base van and truck model in it and the specific variant models are in folders inside however if i want to get the base models I can through resources load because

dir = "Resources/BaseCarModels";

resources.loadall(dir);

will give me all the variant models as well.

I can actually fix this of course, I can place the variant models in the same level so they arent under it or i can "reverse" organize

I can have

Variants folder

and

BaseModels as a folder inside it its just that this reverse nesting strikes me as ugly and it conflicts with how the rest of the folders are arranged so i dont like it.
