I recently bought a large lots of comics. I was adding them to CLZ using Cover Scan and Add to Queue in large batches.
It really highlighted the need for an Apply to All option when processing the queue. It got tiring having to tap the move from wantlist to collection option hundreds of times in a row.
It is on the ideas list to indeed have an apply to all.
It will be a scary button though and no going back.
You’d basically be making a decision for potentially 1000s of comics in your queue while not knowing exactly which ones it is going to change to in collection.
And no way to undo it.
But I’m supposing most users know what they scanned and if they had it on their wish list 
This will likely make the cut at some point in time.
