Old SORs

We finally joined the 20th century & went to SORs in CDK (I had tried for years to get on board with SORs & couldn't get the guidance I needed!) Unfortunately just as we're fighting our way thru the learning pains of the new SOR process we, as so many of you all, were obliterated with Takata airbag orders. Cutting to the chase, I have a long list of SORs that need to be closed. (The reasons they exist vary. I'd rather not talk about it.
) As far as I can see the only way to close old SORs from parts invoices is to void them out 1 at a time. That means lots of wasted paper & click charges. Is there an easier, lest costly way to close old SORs that were generated as parts invoices?
Thanks very much.

Thanks very much.
