Crop is not an import function.
Once the photos are imported, you can crop them with the Crop Tool.
Unfortunately you can`t make a crop preset to apply it in import dialog box
Only after import them you can select all [ ctrl/cmd + A ] > develop module [d] > press the little switch
in the down right corner [photo] > "Sync..." becomes "Auto Sync"
press "R" for crop open your 1st image. Press "Done"
The crop apply to all images automatically
[this is one of the many ways Lr use batch process]
