When you select Multiple end points it images then does validation
Image 5
Then validate and it says failed 2 , 3 validated
Would be nice to list each card in a list, Pass, Fail - Inserted
Then as you pull each card it would chnage, this would allow to find the cards to remove that failed
Its kinda hard with alot of SD card readers as they map different each time
Then you could leave the 3 good and press validate again to make sure
