Hello. I'd like to have a version of randomized storage where the items are placed in the racks in no particular order but fill up all the spaces. Some of the boxes are different sizes so when I try to randomize the placement only one small box is placed in a slot and a good portion of the items stays in the queue. I also tried batching the items before sending them to the racks, for example items of category 3 in batches of 8, but the items still got stuck in the queue.
