Hello Oscar,
To change the content of a label created automatically, you need to change the "Drawing style" content which is used for the view on the drawing.
To give you an idea, you can change the label which will be created for Object presentation > Anchor bolts > Annotation strategy, and choose e.g. "Part name" (which corresponds to %Name token)
You can also go to the GRAITEC Advance Manager > Settings > Defaults > Anchor > Connecting elements > Anchors/Bolts and change the content of the "Anchor name" (which fills the %Name token for Anchors on drawings)
Regards
Philippe
