Options available in a repeated question

Dear Team,
I am building a form with a ‘select one’ question that repeats a number of times (depending on the figure entered in a preceding my target question). Now I want the options available for selecting to be without the option that was selected previously. To be clear, I am first asking “Hoe many SPEs were involved in the process?”. If the respondent says “2”, my question of interest is repeated twice asking “Which SPEs were these”? So I want if they select “Tom” in the first count, “Tom” cannot be repeated in the options available in the repeat run.

Or at least get an error when trying to select the same SPE a second or third time.
