Default Message schedule

Hi all, just a quick one.
I was wondering if there is exposed app for adding message scheduling to the standard app.
I've installed custom roms in the past and it has been a feature. I don't want to flash a room for 1 thing lol.
Also I've looked at the stores apps and they don't add functionality to your default message app but through a different app all together.
I how in not waffling lol and hopefully this makes sense.
