Analytics tracking 2 forms that are linked

Hello,

I have 2 or 3 forms that once customer fills in they redirect to a full finance form.
How do I get this tracked correctly with analytics? At the moment if customer fills in the first form, and then chooses to also fill in the second form, this counts as 2 conversions – though it is the same customer. Is there a way of trigerring this conversions 1x only even if both forms are filled in?

Thank you
