Conditional Fields add or subtract fields groups

I have a festival entry form where I would like to be able to add or subtract field sets depending on how many categories are being entered. I linked to example of what I need to do and was wondering if the plugin Conditional Fields for Contact Form 7 would work to do this. https://kiwanismusictoronto.org/2018-solo-entry-registration/

Thanks so much,
