Slideshow on Second Monitor

[Mark1342]

Xnview Classic has the option: Dual Monitor, Use second Monitor (Browser & Slideshow)
Xnview MP has second Monitor option for full screen only
I understand (from previous answers) the operation for slideshow is to start from the monitor with the slideshow dialog box.

My use case when presenting images at our Camera Club (projector as the second monitor) is to only let the audience see the full screen images. (Seems more professional and it is not as easy to see clearly the slideshow dialog box from the back of the room).

Can I request the option be made available for the slideshow to start on the second monitor please.
