PO Suggestions - Buy All Button

Hi,
I’ve been asked to add a button to the New PO Suggestions screen to flag the Buy option on all rows. Not really sure how to do this. I can add a button to the form, but do I need custom code to loop through the data set and set the Buy flag?

Any help is appreciated.
Thanks.

Why would you need a customization for this? It already exists.
