Office Connector - PowerPoint Issues

Hello,

I am currently working on setting up a template for ARAS Office Connector for Microsoft PowerPoint. By writing a custom VBA script I am able to get the Custom Properties to display on a slide, but the issue I am having is how to have the field/text update when the Custom Property is changed?

Has anyone else created a solution for a PowerPoint template that can solve this or approached this in a different way to solve setting up a PowerPoint template?
