Create loop questions depending on field

I'm doing research on leadership style and I'm collecting data from leader-follower pairs. Thus, I have two surveys, one to be sent to leaders and one to be sent to followers. In the leaders' survey, leaders are asked questions about themselves and their followers. I want to include a field in the leaders' survey that I can ask the leader to indicate the names and email addresses of their followers, and depending on the number of them, to create a loop of the same questions to be asked per follower. My research supervisor told me that this is possible, could you please advice how I can do that? Please let me know if you have further questions.
