Hey everyone. Not sure if anyone is actually here, or if this is really the right place to ask a question. But I was trying to figure out the best way to filter the options available in a field based off a selection in a different field. Essentially the end-user will have the option to select all categories that apply to the item being created in the applicable categories field and then the ensuing field will allow them to select the primary category. I want the options available in the primary category to be restricted by the categories selected in the applicable categories field.

I've figured out a way to do it that involves creating action and rule pairs for each possible category, but seeing as there are a ton I wanted to see if it was possible to filter dynamically based on the selection.
