Seeking solution for cart reservation.

[hotrodjen]

Looking to find out if there is any apps that help with Cart Reservation

example: 1 off items,

customer A adds limited item that has 1 in stock in their cart but before they can complete the check out process 

customer B adds the same item in their cart and checks out before customer A

is there an app or how would i go about seeking a solution to maybe set a timer for these special items to be held in a cart for like 10 mins? Thanks
