New Purchase release communication process to suppliers

Hi Oracle Friends,

Need to understand how buyers can communicate PO release requests to suppliers in the even that ASCP goes down. 

Current process has buyers going into the PO Summary screen and manually exporting all the PO Releases and then cut/paste for specific suppliers.  It's a very manual process and we need to figure out a better process for sending new PO Releases to suppliers if SCP has an outage.

Thanks
