I have added this to my feature request list. The only way I can see this being possible is as a second CSV import because all individuals would need to exist first and the second CSV file would have to contain the entry ID/s of the individual family members so they could properly be created. Honestly not sure which would actually be faster manually creating the families after import of the individuals or creating a CSV file with the required entry ID/s so they can be imported. Either would be quite a bit of work.
