How to access preloaded csv choices not selected in repeat question

Hi and welcome, @aleadalardo! When you get a chance, please introduce yourself. In general, it's better to post a new topic when your question is not identical to a previous one.

I don't use the search() appearance/function myself so I don't have an exact answer for you but you should be able to use the so_far value you've introduced in your form as an additional filter. You can see here and especially 6 near the bottom for ideas.
