how to let pre-specified numbers of agents staying at an area at the beginning of simulation waiting for pick up?

Question

I would like to specify a fix numbers of agents that are shown at the beginning of the simulation so I can move them to the other place. However, the agents are generated continuously... Do you know how to make a pre-specified population and let them wait at an area instead of generating them continuously ??

Thank you!
