Google Sheet and Contacts

erf

Is there a way to import/export multiple contacts for each company? I work for a non profit and want to be able to attribute a donation to the correct person/email but then roll up an annual receipt for a family (if a couple filing taxes jointly donated individually over the course of the year). Google sheets doesn't have a field for importing multiple contacts and it doesn't export those additional contacts either. Is there a way to do this?
