Ipad

Hello, I recently switched to lightroom mobile on iPad to have more flexibility ,and I have a ssd Samsung t5 where my files are located, and I have 2 questions if someone could answer would really help

I was tryng to pass to lightroom all the folders that are organised with the photos, but lightroom just alowed me to pass the photos not the folders, i would had to go trough each folders and import the photos unorganised, can I transfer folders with folders and photos organanized? Can I select one folder with a lot of folders and show me all photos to just select the ones that I want instead of having to go three each folder ?

the other question is if it is possible to when importing photos from the ssd to lightroom the photos could be storage on the ssd not in the ipad as in the iMac ?
