It’s been some time since this suggestion was brought up. I feel it’s worth mentioning there’s a number of similar/related suggestions which already cover that specific use case in a wider context. Specifically there’s one suggestion thread discussing an option to have all library sort options available to sort a collection in ascending/descending order – including the option to sort it randomly.
I suggest you comment/vote in that thread to avoid distracting or cannibalizing votes from each other.
