Choose local or online Metadata Folder by Folder

In our Blog by Version 5.7.2 is written, that I can toggle between local and online metadata folder by folder.
But, where can I setup this ? I can´t find this option…
I like to use only local for Movies, and for TV Shows I like only to use online metadata. I have two Folders ( Movies / TV Shows ) with Subfolders for each Movie or TV Show…

Kind Regards

On a folder you wish to change, do a long press on the remote pad and a menu should be displayed which allows you to change the online/local metadata selection.
