Generate a Sprite Atlas in script editor

Hi, is there any way to create a list of sprites on a texture (turning it into a sprite atlas) from a script, and if possible, could I get some guidance on how to do it?

For context: I have a bunch of sprites, and I want to create a new sprite atlas that contains copies of them with added effects (and maybe different sizes), for automation purposes (not at runtime).

EDIT: found my solution You have to use TextureImporter to pass a SpriteMetaData array, that contains the names and rects of your sprites, like so :

 TextureImporter importer =  (TextureImporter)AssetImporter.GetAtPath(AssetDatabase.GetAssetPath(texwrite));
 
  List<SpriteMetaData> spritedatas = new List<SpriteMetaData>();
         for (int i = 0; i < 10; i += 1)
         {
             SpriteMetaData data = new SpriteMetaData();
             data.rect = new Rect(i*10,0,10,10);
             data.name = "sprite_"+i.ToString();
             spritedatas.Add(data);
         }
 
         importer.spritesheet = spritedatas.ToArray();
         EditorUtility.SetDirty(importer);
         importer.SaveAndReimport();
