Key to add bolts in the clip repeaters

[Ken_Repeaterman]

The problem with repeaters is that you can't just add the required number of bolts in the clip, before that you need to shoot all the bolts and empty a clip and only then start reloading.
If feasible, I suggest to make a button to add the missing bolts in the clip from the stock bolts player without prior emptying clips. As in other games.
I apologize for my English, hope you understand me
