Is it possible to create grid matrix templates via csv or script?

AI generated answer (using internal Slack threads):

Based on the conversations provided, it appears that it is possible to create grid matrix templates via CSV, but it is a two-step process. The first step is to import the parent items, and then the child items (variants) are imported with the parent item's internal IDs set. It's important to note that the Matrix Options lists must be populated first and their internal IDs should be referenced in the child item import. However, it's not clear if this process can be automated via a script. The conversations suggest that scripts can be used for other tasks, such as creating item fulfillments based on a CSV file or updating work order locations, but there's no specific mention of using scripts to create grid matrix templates. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
