Powerpoint linked custom properties automation

[David]

I am trying to update text that is linked to a custom property in powerpoint.

In excel it can be done with the following code

oDoc.Names(docObj.linksource).RefersToRange.Value = hm.Valu

In Word you can use thi

Set oRange = oDoc.Bookmarks(docObj.linksource).Rang
oRange.Text = hm.Valu
oDoc.Bookmarks.Add docObj.Name, oRang

I can’t find any way of doing this in powerpoint. Is there a way to change this value programmatically
