Delay playback when an amp is waking up from standby

As an owner of NAD's M33 integrated amplifier and when it's waking up from standby, I want to delay playback of a song from, for instance, the BluOS app or Apple until the amp is ready to play.

Motivation: Imagine that the amp with an integrated BluOS module is on standby. It usually takes 5-6 seconds for the amp to power up from standby before it's ready to play music. But when you use the BluOS app to play song and turn on the amp at the same time, the song plays immediately so that it's already 5-6 seconds ahead when the amp starts playing. That's not so convenient, and it would be better if the song starts play when the amp is ready.
