Hello. Please correct me if I'm missing something, but I'm curious as to what the reason is for only being able to "ingest from selection" only from the "frontmost" contact sheet?
It's terribly inconvenient to not be able to open several contact sheets which reflect several folders on an SD card for instance, select those images you want from each sheet, then doing the ingest and do other things while it works. You have to run the ingest process several times for however many contact sheets you have.
