W2 EXPORT FILE ERROR WHEN UPLOADING TO SSA...KIND OF EMPLOYER field

We are getting erros when uploading our exported data to SSA...the error says we don't have anything in 'KIND OF EMPLOYER' field....That is because Vantage 6.1...does not have a place to enter this info...Can we edit the exported file somehow to include this and then upload? I assume it's only on the first record (the employer record)....Haven't had maintenance for years and doubt that Epicor is still producing W2 updates for this version anyhow....
