I'm trying to come up with a macro that mimics Microsoft Word's Document Properties but in PowerPoint. To do so, I want to automatically update the Text to Display of all hyperlinks that have a specific Address with a custom PowerPoint property.

For example, I have a custom property "File Link", and I want to plug the "File Link" property text (e.g., www.excelforum.com) into the Text to Display for all hyperlinks that have the Address "#URL" for the hyperlinks.

I've cobbled together small tidbits of VBA that help me expose document properties, but I cannot for the life of me figure out how to do the find/replace on specific hyperlinks.
