Submitting a 1099 electronic file to IRS that contains only the corrections. (PeopleSoft AP version

One of our institutions has the following situation:  They have already submitted their electronic1099 file to the IRS which has been accepted and they have run the WTHD_SENT process.   One of their vendors has notified them that this vendor should not have received a 1099  and the institution agrees that the 1099 should not have been submitted for this vendor.   They do not want to resubmit the whole file to the IRS again.  Is there a way  to generate an electronic file with just the correction for this vendor or do they just need to submit the correction manually via paperwork?
