Rekordbox DJ - Interface 2 (External Inputs)

Hi, I'm just wondering if what I'm trying to achieve is possible. I have a xone 23 mixer but I would like to be able to use rekordbox dj effects with real vinyl. I know using rekordbox dj effects with a dvs system work fine could I connect my turntables to the interface 2 soundcard and set the rekrdobox dj to "External Input" so that I can then use rekordbox dj effects when using real vinyl? Something similar to traktor's live input option? 

Thanks
