Is it possible to use VBA in MS Project to modify timeline bar descriptions? I understand the timeline bar description use the task.name but is it possible to point the timeline to a task.text1 string?

I could not find much on the project’s timeline object or its properties. It appears to me that what I am asking about above is not possible in ms project but thought I would approach the community before fully losing hope. (https://learn.microsoft.com/en-us/office/vba/api/project.timeline)

I have used VBA to place tasks on timelines but do not have the VBA objects/properties in a library to address the need described above.
