My Cloud Ex4100 Newly inserted drive becomes Public 1

Hi there! We’ve just added our 4th drive to our MyCloud EX4100 and it has always baffled me that I can’t tell the system which drive should be 1, 2, 3, or 4. I’m limited in my knowledge of systems like this, so maybe it’s user error. Each of the drives are set up as JBOD because we purchased them one at a time. It doesn’t matter how they are seated in the EX4100. The newest drive has always become Public pushing the next one to Public 2. Now with the new drive, what was Public has become Public 4, Public 3 became Public 2 and Public 2 became Public 3! It shouldn’t be a huge deal except it really messes up my Lightroom catalog! If there is a way to tell the system which HD should be 1, 2, 3 or 4, I would REEEEALLLY like to know :). Thanks so much!
