Instant Doubles lock with DDJ SX and rekordbox Performance

Hi,

I saw that, when I set 'Eject/Load Lock' as 'Lock' in rekordbox Performance mode, the 'Inst. Doubles' function of my DDJ SX is not locked on a playing deck and it still works.

Is there a way to lock also the Inst. Doubles function? Sometimes I accidentally press two times the load button on the playing deck and there's no protection. It's nonsense that Load is locked but Inst. Doubles is not...

Thank you.
