Remittance Addresses to populate on 1099s

To the best of our knowledge in order to have the remittance addresses populate on 1099s, we have to go change the default address from P01 (purchase address) to R01 (remittance address); process the 1099 then go change all back to P01.

Is this the only way or is there an easier way of doing this? We were told the P01 addresses need to be the default otherwise we would keep the R01 as default.

Thank you,
