P: import - make me choose whether I want to see all folders COLLAPSED by default

I use the 'Destination Folders' function when importing images. When I do not delete previously imported images from my memory card, the number of folders (different dates) in LR shows starts to pile up. This then starts to takes soo much time to render all thumbnails, as all folders are by default expanded. I would love to see a toggle to see all folders collapsed - which is a setting that's then remembered for the next import.

Then I would only have to 'open' the most recent folder (date) and leave all other folders as is.

Another optimization would be to show the latest images at the top. I currently don't know of any sort option
