Possible to "lock" device folders to be scanned?
I usually configure my devices to only scan the "Books" and "Download" folders, to save time whenever the device is connected to Calibre via USB.

Unfortunately, whenever one adds folders, moves things around, or renames folders on the device, these will be automatically included in Calibre’s device folder scan, leading to enormous RAM waste and endless scanning times (especially when using Android MTP).

Just took me almost half an hour (!) until Calibre showed the books on my tablet, just because I had installed an additional reader and some new StarDict dictionaries that each contained thousands of images in their "res" folders.

So my question/feature request: Would it be possible to configure device folders to be scanned and then somehow "lock" that selection, so Calibre would not go and look for new folders/changes when connecting?
