RP Advanced Pedestrian Spawner (Idea)

So something that would be very awesome for those who like to go hardcore RP like I do, is a trainer that can spawn pedestrians and or vehicles, in a radios of the player or selected area via pause map way-point.  The catch is, you can also have them do animations, such as smoking weed, have 2 random peds fighting, swinging a melee weapon hitting objects.  You can also have them flee from the area or have an option for them to take cover and sneak around trying to evade you.  This brings in the skills of us officers to try to look in the alleyways and find the suspects.  All the options would be available like radios size, how many peds, their animations/actions, etc.  Same with vehicles, spawn a reckless driver, or a vehicle with damage.  In essence, we would have control of what is spawned but would have to find it in the radios and RP it out.

I don't know if you understand this or if it is even possible.  Shit even add your ideas and options into it but would be a cool little mod.  I know the simple trainer has some of these options but they are limited to spawn right at your location.  I want to look for them or have that feeling of driving up not knowing what it could be.
