I think I was asking it here too already, seems a mandatory feature and probably "easy" to implement.
The other thing I asked already several times, see one actual post a bit lower, I would like to export single games, or multiple without the .xml file getting overwritten. I exported once around 200 PS2 games, so you can imagine the time it takes, so when I wanted to add 5 others, I found myself only with those 5 games in my LB library and had to redo the whole process again with 205 games.
The games stay untouched, as is the media, but the platform .xml file gets altered with the last exported games which makes no sense to me. At least with the export media only, or just export .xml it would be possible not to go through the whole process of exporting everything. You can backup your old .xml file, copy the content from the new one to it, and copy it back, but that's cumbersome.
