You no longer are given a choice of custom naming for exported files. Instead you are given the choice to edit your import naming preset. Although customer service showed me that changing the preset here doesn't alter the preset rules, this is EXTREMELY CONFUSING. I shouldn't have to contact customer service to determine that I can edit this section without affecting my preset. The previous method gave a choice of a custom name for the exported file. This allowed you to know exactly what you were renaming. File naming is an extremely important function in LR. There should be zero confusion as to what you are doing with this. Please fix this!
