Is there a way to spawn vehicles/generate flow in a non-deterministic way? What is the use of the seed parameter in the config file?

I have two questions that I wanted to ask:

1. The current approach of generating flow is deterministic where a car for each direction spawns every x seconds as defined in the flow file for that direction, Is there a way in the simulator to generate these flows using a distribution instead and not using a pre-defined interval?

2. In the documentation, the config file has a seed parameter, what is the use of this parameter? Is it used to randomize flows in a certain way?
