Can I add multiple items at once to a favourites submenu

[irish]

I have a long list of stuff in my favourites menu.
lets say some of those items are links to youtube, and some others are links to dailymotion, and others
are links to stuff on my hd.
So, i want to create submenu's for dailymotion, youtube, and stuff on my hd.
Is there way for me to move a number of items at once to the youtube submenu and so on?

Currently it's not possible with the SMPlayer favorite editor.

However the favorites are stored as m3u8 files so I guess you can edit them with any application that can open m3u8 playlists.
