I would like to be able to export large numbers of images at a time with the same size, compression, etc. and be able to save these export settings so I can use them again. Does LR have this ability? What is it called?
It is called an Export Preset and is available in the Upper Left Pane of the Export Dialog. You click [Add] to create a perset. After created, Right-Clicking or CTRL clicking will allow you to rename, update, etc.
