I am working on a cable robot project where I am using stepper motors to roll and unleash the winches to control the position. In order for the object to go to a certain position, the motors need to take a specific number of steps.

The pulse generator does not let me define the number of pulses. What can i use or what should i do in order the generate pulses with a certain amount?

(I can not use a time based solution such as; use the time it takes for 100 pulses to be generated and stop)

Use a "Counter Limited" block. Set the limit to be a large number and sample time to be 1. Compare (<=) it to a Constant block (the number of pulses you want). Use the output to enable an "enabled subsystem". Inside it is a Pulse Generator. Set the period to be 1 and 50% pulse width. Run simulation in discrete with 0.5 simulation step time. You will get the number of pulses you want.
