Archi-lab combine by pattern

I have an old script that uses the Combine by pattern node from Archi-lab. I am opening the script in Revit 2021.1.1 and have loaded the latest Archi-lab package 2020.25.18, but the node isn’t loaded. I’ve looked and Googled, but can’t find any information. Has it been discontinued or am I missing something. Is there an alternative?
