Single-player Level Restart

Hi, I was thinking a level restart option for single-player would be amazing for those who want to get the no dying achievements.
It would be better/faster option then Finishing the entire level or leaving the game and have to load back in.
For me, i got a little annoyed that i had to leave and load in every time i died and it would be more relaxing if i could just hit a button and it would restart at the beginning like if i had just join in to the game.

Thanks for your time,
Have a Wonderful day.

I frequently think like it’s intentional not to make too easy
