Change bullets for different indentlevels

[fernandezdiego]

I'm trying to change the bullets used in a paragraph's different
indentlevels to a specific character.
I seem to be able of changing this only in the master slide, e.g.,
ActivePresentation.SlideMaster.TextStyles(ppBodyStyle).Levels(1).ParagraphFormat.Bullet.Character
= 77

Coundn't find a way to do it for a particular textframe object.
Help is appreciated.
Thanks!
