Custom Property Tab API?

Looking for info on how to refresh data in the CustomProperty Tab via API.

The issue I am attempting to solve is this:
If Custom Property fields in a model are changed through the API,the fields in the tab get out of sync. If the user saves the model,the custom property values revert to the values in the tab. I needa way to add a call in my code to reload the properties in the tabagain after an external change is made.

Almost nothing is mentioned about this part of the Task Pane in theAPI help, from my searches. No API stuff in the Property Builderapp help either.

API info on this area would also allow relational changes to otherfields, and error-proofing user inputs.SolidworksApi macros
