I am in the process of digitising 14,000 plant samples. The photos have to be exported as .NEF to one folder and as .JPG to another. Is there a way to call an export preset from another or concatenate the contents of two export presets into one. My efforts into the latter option will only export to the second location regardless of their order in the file. I am using Lightroom 6 stand alone. The answers I have found on the web seem to apply to versions below LR 4. There will be various people using this system and the elimination of human error is tantamount.
