have a option to buy a terminal in base or computer.
buy drugs from shops as normal, but once you have bought the drugs you can put them into the computer like a locker.
now with the computer or terminal you can set up options.
for example option 1 you can call tank and set it so that with tank it takes beer phyco buffout nuka cigs wot ever.
option 2 sniper and set drugs
you can set up different types of options call them what you want like your chars names or the terminal already has them installed you just got to assign what drugs you wish to take from them.
but with the terminal you cannot buy drugs, purchase them as normal, but install them into computer once bought.
saves time from taking them out individual each time.
