Possibility to assign a key to each save slot?

Hi, I would like to knows if there is any possibility to assign a key for each slot (save and load) instead of using increase and decrease key? for ex: key number 1 for slot 1, key number 2 for slot 2 , etc … It’s would be very useful in ordrer to use hyperpause menu on hyperspin witch need to have unique keys for each slot (save and load) to use the save function. any idea ? thanks regards
