Option to enter sleep mode immediately or 5 minutes with sleep timer

As a user of the BluOS app on both desktop and mobile app, Iwould the option to put the player in sleep mode immediately or with, for instance, 5 minutes as option on the sleep timer so that I can more easily control when to turn of my amplifier.

The sleep timer currently has these increments: 15, 30, 45, 60, 90 minutes.

Info: I'm using BluOS to control my NAD M33, both from a desktop app on a Mac Mini and on a iPhone and iPad. Hereby screenshots from the iOS and desktop apps with the sleep timer highlighted.
