During File Import, if you tick 'Into Subfolders' for file Destination supercedes "Organize: By Date".
It would be far more convenient if one could import "By Date" and then "Into Subfolder" - as oftentimes when shooting events or high volume starting to organzise between SD-cards or even in between shoots is highly convenient.
One Day I might be importing a number of jobs during the day before I can actually come around to manage them, and then if they had all imported on the same date into Different Subfolders, that would be extremely helpful.
Additionally, if importing into a Collection, you should be able to tick 'Create Subfolder in library' or something of that effect. It would really underpin the organizational element of lightroom and encourage people(myself included) to make full use of Collections. Which are such a powerful tool.
THank you for the consideration.
