Protoolkit equivalent for "Save as Mirror Assembly" and "Mirror part"

Hi all,
Is there a toolkit equivalent of Creo UI operation, “Save as Mirror Assembly” or “Mirror part” available? I’m trying to automate the mirroring of an existing assembly and the associated drawing using protoolkit without recreating the model from scratch? 
After the mirror operation completes, is there a way to update the existing drawing with its dimensions to reflect the mirrored geometry?
Any pointers would be greatly appreciated.
Thank you.
