Recursively Scan Picture Folders to Generate Cashed Thumbnails?



I have many folders (and sub-folders) with pictures (and Videos).
When I open a folder, Kodi scans the files to generate cashed Thumbnails. This can take some time.

Is there any way to have Kodi scan all the folders recursively to generate the Thumbnails w/o the need to manually open each folder individually and wait for the scans to complete?
