How divide assets into different folders when importing FBX?

As we know, it generates several assets like skeletal mesh, physics assets, materials etc when importing an FBX file.
It means a disaster when I import couples of FBX files. I get an idea that creates a plugin or something to put the different assets into the folders created before. For example, if the folder named Anime exists, all the anime assets will be put in that folder when importing FBX, otherwise, nothing changes.
But I don’t know which source codes affect the asset importing. I don’t program regularly. Thank you in advance, whether your suggestion is useful or not.
