Sleep Timer: Option to Finish the Last Song Before Stopping

I like to set a sleep timer of around 20-30 minutes, which they have and I like. But at the end of the set time, the song stops. Doesn’t matter if it’s in the middle of a song or not. I feel like there should be some kind of box to check off that asks, finish last song or something like that. This way I can fully listen to the last song and don’t suddenly get out of it.
