Concerning implementing ${__StringFromArrayAtRandomIndex('3', '2', '54', '42')}.

Suppose you can easily implement your scenario using e.g. BeanShell Sampler / BeanShell PostProcessor with a bit of code.

E.g.:

• Set your source variable (via e.g. User Defined Variables):

  Name        Value          
  categories  3,2,54,42,37
  

  (i.e. use comma as delimiter, no spaces before and after comma).

• Use add BeanShell Sampler/PostProcessor with the following code:

  import java.util.Random;
  
  String[] categories = (vars.get("categories")).split(",");
  
  int idx = new Random().nextInt(categories.length);
  String category = (categories[idx]);
  
  vars.put("categoryId", category);
  

• Refer further in the script randomly picked form list value as ${categoryId}.
