It's somewhat problematic to remember the last directory, because it could have been to a location that is inaccessible (i.e. a removable drive), to a cloud folder that might require authentication, etc. If enough users want this, I can try to make it happen, but there could very well be an error that occurs after starting the batch import if the folder can't be accessed. My hope is that users will understand in this situation that they may need to just select the folder again, especially with cloud folders where the saved oauth token may need to be refreshed. While I can see the appeal in saving the folder in some situations, it's not terribly inconvenient (in my opinion), to tap the folder, the local file, then tap OK, because the file browser should default to the last folder you browsed to (and the file browser correctly handles situations where it can't access the last viewed folder). 

It definitely sounds to me like what you really want is an automatic sync option to a local directory. I am going to be working on an automatic sync feature later this year, and I'd like to add support for local and network drives with that, so I'll see what I can do.
