DJM 450 - ability to pre-cue Rekordbox sampler when in HID mode?

Hi

When using the DJM 450 in HID mode with Rekordbox DJ, the auxiliary volume control on the DJM, controls the volume of the sampler in Rekordbox.

The questions is, can the sampler be pre-cued using the DJM when the auxiliary volume is set to zero?  There obviously is not a cue button for the auxiliary on the 450. However do the cue buttons on channels 1 & 2 also work as cues for the auxiliary input (or maybe the master cue button)?

Many thanks
