AddExplodedInstancePieces without...adding the instance...pieces?

I’m using AddExplodedInstancePieces to get copies of block geometry to do some stuff with, is there an equivalent to this that doesn’t actually add the geometry to the document, so I don’t have to track down and delete what I don’t need?

# ObjectTable.AddExplodedInstancePieces("name" , "false" , "**true**")

What are you looking for - just the geometry of the objects in the block instance?

Maybe: (a bit cleaner)

import rhinoscriptsyntax as rs
import scriptcontext as sc
import Rhino

obj_id=rs.GetObject("Select block instance",4096)
if obj_id:
    inst_obj=sc.doc.Objects.Find(obj_id)
    rhobjs=inst_obj.InstanceDefinition.GetObjects()
    orig_objs_geo=[rhobj.Geometry for rhobj in rhobjs]
    #orig_objs_geo has the untransformed geometry of the block definition
    for obj in orig_objs_geo:
        #apply the instance transform to the original geometry
        obj.Transform(inst_obj.InstanceXform)
        #now choose which objects you want to add here...
        sc.doc.Objects.Add(obj)
    sc.doc.Views.Redraw()

?

Something like that I think? I need copies of some of the geometry in various instances.
