Title says it all. Not really a big deal so don’t bother if it requires significant effort. But I was just stacking some images that included a pier flip and when I do that, I like to stack images from each side of the pier separately so I can remove the gradient before combining. This avoids dealing with complex gradients often encountered with flipped stacks. While sorting through the files trying to figure out when the flip happened, it occurred to me that a side-of-pier file name token would make it a bit easier to sort the files.
