you can add folders to any type of resource, I might be somewhat wrong there, but in general, that's true.
So, if your furniture has been saved as symbols, you can add a symbol folder for the 1059s furniture. In turn as you bring those symbols into a file, you can also add a textures folder for that furniture.
I would create a file for that furniture, add folders as needed, then save the folder in my library which is a directory on my hard drive. I would then add that file as a favorite in the RM
