Have 175+ items I'd like to add to an "Incident-Additional Field"

Instead of adding them one by one. I was planning on using Field and Forms and upon Form load, add in the options.

(Imagine typing in and managing these fields with 175+ values manually)

According to the help, it says I am well within the range of having up to 25,000 items.

Cannot find anything in the rules that state how to load in these values to a variable.

Anyone else attempt this before?
