Add Shared Parameter to Family

Hi everyone, I was wondering if anyone can help me out here. I work for a manufacturer and we have quite a large library of Revit families which need updating. New parameters need to be inserted into each family and I am wondering if it is possible to add shared parameters from a txt file or from an excel file? I tried Add Shared Parameter to Family node from archi-lab package but I’m not sure how it works. I got this far with it. Any help is much appreciated. Thanks, Bogdan
