GL Offset in P0411SV Speed Voucher

We've set up GL offsets to manage several GL bank accounts for one company.  This works fine with the standard P0411 but the P0411SV Speed Voucher does not have a place to enter the GL Offset when creating the voucher.  I know that you can default the GL offset from supplier master when using P0411SV but our suppliers will cross multiple GL offsets so that is not an option.  Is there a way to get a GL offset on a voucher using P0411SV other than GL class code from supplier master?

Thank you
