SEPA Payment format structure is using wrong definition message Pain 001.001.002. we need Pain 001.0

We are in the process of implementing electronic SEPA payments for the first time and our bank has informed us that we were using the wrong instructions (pain.001.001.002) and that we should use pain 001.001.003.  We have been trying to figure out how we can incorportate the new pain .003 for us to use and I was able to find the following on the support page.

14747792 - SEPA PAYMENT FORMAT STRUCTURE FOR MULTIPLE PAYMENTS CREATING SEPARATE LOGICAL GR

However, the patch that is recommended (14747792:R12.IBY.A) to fix our problem also fixes 443 other bug fixes.  Is there any way that there could be a single patch to fix our problem without having to perform extensive testing on our end soley for this one problem we are dealing with?  This is a huge setback on our global go-live project.
