Can I apply GDF from Doc ID 1581836.1 once for multiple POs?

Hi Community

I have a identified a number of POs (34 of them) for which I need to apply the GDF from Doc ID 1581836.1 Generic Datafix to Correct Encumbrance Value or Active Encumbrance Value for Standard Purchase Orders and Requisitions.  

The documentation suggests that the  fix script  Enc_amt_fix_single_doc.sql is designed to be run for an individual PO but this would mean I'd have to run it 34 times!  Therefore, I just want to check if I can run it for once for multiple POs at the same time rather than one by one?

Thanks
