[users] export pdf from custom slide show

[Patapon]

I have created a custom slide show in order to repeat some one or more
slides when needed.
I want to export to a pdf with the same play order (see below.) as the
custom slide show since pdf is more suitable to be handed out to my
students.
 (for example: slide 1, slide 2, ... , slide 10, slide 3, slide 4, slide 11,
..).
Is it possible ? or we can consider it to be feature request.
