How do I create an action to batch-replace complex multi-line text strings

Hi All,

I'm brand new to this community and am new to using the Action Wizard as well. My boss asked me to build an action for my coworkers to batch edit our invoices. Ideally they should be able to just hit "start" and let the wizard do all the work for them. (This will be a temporary fix for the next 4-6 months until we get our new invoicing software).

We need the Wizard to:

1. Search all PDFs in a folder and find those that contain an incorrect return address

          --We have multiple divisions and only one of them has the incorrect address

          --All of the incorrect invoices have a slightly different naming convention so, if needed, we can have the Wizard search by document title

2. Replace that return address with the correct return address

If the above is impossible, maybe we could manually isolate the incorrect invoices, and have the wizard paste a new text box over the old incorrect text?

Thanks all!
