I am trying to import race participants who are running in various races at a race event hosted by my organization. Some participants were eligible for early-bird pricing for their race. However, the import file from our registration website only gives me the race they registered for and the price they paid. I have a registration type for each race/regular price/early bird price combination. Is it possible to conditionally match an import field to a particular registration type based upon the race entered and the price paid? For example, can a person who running the 10km race who paid the early bird rate be linked to the 10km early bird registration type as opposed to the regular priced 10km registration?
