Update of choice list in a repeat count

A learner in xlsfrom. I’m trying to develop a system with a choice list of schools with a list of teachers to choose from (Select_one) in a repeat count. In the first repeat, I select the teacher and complete his/her data but in the second and subsequent selections, I wouldn’t want the already selected teachers to seen in the list of teachers to be selected.
Is there a way to do this? Let me know if the sample data would be needed.
