Python in Deltagen

Hi everyone, I am using Deltagen 22 RF1 and have questions regarding Python.

Q 1 - I would like to know how to select items in the Deltagen 'scene tree' through Python code. For example if I have a list of items, how do I select all of the items in the list stored in a Python variable (as though I have manually selected them in the scene tree)?

Q 2 - Is it possible to 'dereference objects' (through Python) on items that are in an active scene? I cannot find how to do this in Python. Similar to the script in the documentation regarding flattenTransforms().
