Additional Emergency Vehicle Slots

Hello!

So, my adventure today was entirely focused on the addition of vehicle slots - predominantly aimed at emergency vehicles. I downloaded a mod -

LML - Extra Slots 2.3.0

- and it of course provides the game with a low number of additional police slots. My question for you all is given that I have all the data in front of me from this mod, could I, in essence, copy / paste all data from the corresponding files, and create more add-on slots for even more police vehicles? I was able to configure my first add-on vehicle earlier to spawn with Ultimate Backup after about 30 minutes of tinkering, and now I’m slightly addicted to having a huge variety of emergency (specifically police) vehicles in the game. So my end all be all question is could I theoretically create more slots using the data from the mod, and if anyone could narrow down what exact file paths I would need to edit, that would be amazing. Any assistance would be appreciated very much!!
